I just bought bike with Sram rival for my wife. It's her first road bike and I put the shifting in sequential mode. Now she doesn't need to deal with front mech at all. You have 15 gear trough whole range just up and down. I think this mode and nice gearing are the perfect combination for the beginners.

I’ve always ridden Shimano until I bought my Trek Checkpoint SL6 with Sram ETap and for me I can’t really fault it (apart from the weight). Great review again David. 👌

Hats of to you David, love your content and this comparison vid is just perfect imo, congrats!

I'm looking at several Trek bikes that offer SRAM eTap groups sets. Another video described the ease of mixing and matching SRAMs wireless components which to me is super important for customization. In the past I never considered electronic shifting due to the high cost (especially of DI2) but with the low cost, great performance and ease of customizing, SRAM is the winner.

I build my Specialized Allez Sprint with 105 Di2. It is an amazing groupset. I have another bike with Regular 105 and the breaking performance increase is really amazing. For those who like the SRAM "left up" right down" shifting- I too think that this is better - thats why I did configuire my di2 to do the same. If then full syncro shift is used you only need the two leavers. But I like shifting the front by myself which is why is also set front down left and front up right. Easy with the app

David - well done for coming down strongly on one side rather than fence-sitting, especially as the newer product lost in your comparison. I started with SRAM and have it on 2 bikes (various combos of Force and Red, with a mullet on my gravel bike). I like the ecosystem - from the app to the wide variety interchangeable parts (i switch out 1x and 2x and various other components frequently enough to care) - and the incredibly intuitive shifting method. Also the fully wireless set up is just easier to live with, and I charge so many gadgets on a daily basis that I automatically charge at least one SRAM battery each week. I recently got a year-old road bike that came with Shimano Ultegra Di2 11-speed, and I’d say it wins on shifting smoothness and speed, and I love the buttons on the end of the hoods - which I’ve mapped to change pages on my Garmin head unit. If I had to choose, it would be SRAM FTW, but they are both a joy to use.

Great review, thanks for that!

Thanks Dave - a great practical review. One thing you didn’t mention though - was Shimano’s delinking of their DI2 systems to Hammerhead Karoo units. I have a Wahoo Elemnt but will seriously consider the Karoo when I have to replace, and ideally want a group set that it integrates with. So - SRAM comparability also better then 105 methinks

Great vid by the way! 👍 Keep up the good work!

hi david, great video and comparison between the two. i realize your comparison was for road use, but in 1x mode and with the XPLR rear mech and cassette, you can have a pretty amazing all-road/gravel bike groupset as well. i run this on my cervelo aspero with a 10-44 rear cassette and it has been surprisingly flawless - historically i have never liked SRAM products at all. i came from a GRX 810 groupset and while the ergonomics are better on the GRX (this is obviously a very subjective topic), for me, the Rival hoods are really not terrible and the shifting is just flawless, every time. i do hate being tied to making sure i have battery power before heading out on a ride, but with lights and a wahoo on board as well, it's not much extra stuff to deal with. one additional item to add to your video is maintenance - i find bleeding shimano brakes way nicer and easier than SRAM - it took a lot of bleeds of my Rival brakes to finally get a decent lever feel. also, ditching the stock organic pads in favor of some semi-metallic pads made a HUGE difference in brake feel - they now feel almost as good as the GRX brakes. i also love the customization and integration - like how i can display the gear selected on my wahoo display - together with left/downshift and right/upshift, it's kind of like shifting with the paddles in my DSG-equipped VW Golf R. :)

Thanks for this video. Been trying to get my head around the differences, as my next bike will more than likely be equipped with 105 Di2 or Sram Rival etap (if the supply issues that have plagued us ease ever so slightly that is). All my previous bikes have had Shimano in one form or another, and I know no one who uses Sram, so videos like this help a lot.

David - great job as usual! I bought, with confidence, my Trek Domane with Rival solely on your Rival review several months ago. You didn't steer me wrong as it's clear to me at least that Rival is the best option at this price point! I couldn't be happier with the groupset.

Great comparison video & very informative with lots of useful information 👍🚴‍♂️👍🚴‍♂️

Fantastic review David! It's helped me decide to go for Sram now. Can't wait👏👏👏

Very informative and really can’t argue with much at all.

Great stuff David as usual!👍🏻👏🏻

Informative review. 🙏. The prices and weight of their groupsets is utterly insane, I had no idea. Crazy money and very heavy! Currently have a mix of FSA slx crank, ultegra and 10 year old 105 shifters 10speed mechanical looking for sensible light upgrade.

Hi dave thanks for this video, looking at choosing a new road bike and your groupset comparisons are very helpful. In your speed test both groupsets were in default shifting mode, can you increase the speed of the shifting on both groupsets, could possibly change the end result? Id also be interested in the front mech speed.

I‘ve been firmly in the Shimano camp to date. But I found your review pretty convincing, especially in the areas of gearing options. The one thing I‘d love to learn about is reliability. I seem to remember that some folks had troubles setting up their Sram „systems“, chainline and such. Is there anyone here that can comment?

Having ridden with rival axs levers and now the new ultegra levers, I prefer the ergonomics of shimano but the shifting of sram is my preference. Also gotta facter in sram's mix n match. Shimano needs to bring in a new grx di2 to compete with sram's eagle and xplr line

Thanks for the this great video, looking to get a brand new Ribble CGR Sl with electronic, from an old 10 speed campag veloce bike. Always had Sram in my head as one i wanted until 105 DI2 came out.

I'm ordering a bike with Rival AXS, the main attraction for me was price of the bike and the range of gearing. Will be set up with a 10-36 cassette on the back and a 46-33 on the front. That's going to give me great range for climbing the hills in my area. I've had Shimano groupsets prior to this and I'm looking forward to trying SRAM.

I have 2 Ultrgra Di2 bikes , but, when I built a new bike this year I went for Sram for the reasons you state. I find it interesting that My Sram Rival shifts the rear mech better than the Ultegra,but, the Ultegra shifts the front better and since you shift the cassette more.......

Spot on review.... I have Rival on my Vitus and have been enjoying it. Have 105 mechanical on my Colnago and have ordered 105 Di2.... Love Shimano ergonomics

Thanks for the review! For the disc brake stopping distance test, tires and total system weight should be factored.

Thank you for clarification. 🎉

Just ordered a BMC urs two with Etap rival axs, never had electronic looking forward to it arriving today!

I was initially put off Rival by the weight but it was all that was available when I got my SL7. I’m now a bit of a fan…the lever set up is great and I much prefer the removable batteries and true wireless configuration. The app is good too. I have had some issues with chain drop on front mech but not very frequently. The power meter option is great!

Great review by the way

Tons of fair points, thanks for giving a side-by-side look! I agree that SRAM is probably the best choice for most “average” consumers. As a note, the two sections that I think might have been missing in a proper look for me were shifting speed and braking. I’m not worried so much about how fast I can get up/down my entire cassette but how fast things communicate between pressing a button and having the derailleur react. Both are obviously very quick, but I know Shimano’s fully wired system wins out - I’d be curious what their semi-wireless is like. One thing about needing to press both SRAM buttons for shifting the front mech is that it takes just a fraction of a second longer (perhaps as the components wait to see if the other registers tos hift the front mech vs just moving up or down the rear). For braking, four inches difference seems fairly negligble, but braking feel (modulation, bite point adjustment, etc.) is way more important. SRAM might still win out here, but I’d be more interested in seeing a comparison of those rather than just full stop power.

I haven't finished the video, but where my SRAM Rival group definitely loses for me is the ease in removing the crankset. I bought the Quarq power meter shortly after buying my Roubaix and the install was a piece of cake, the crank came off very easily........ the first time. Now, when my power meter started acting up and I was needing to send it back to SRAM, I couldn't get the crank off again to save my life and to this day I haven't attempted it again. And I didn't torque the bolt either, just snug with a light pull of my pipe-extended socket wrench. I'm just glad the the problem I was having with the power meter crank arm solved itself and hasn't crept up again so no need to send the crank arm back to SRAM. My theory was the update to the firmware was what caused the problem(it wasn't displaying power, just cadence). But I just LOVE my electronic shifting! It's totally unnecessary, but now that I've ridden nearly 1500 miles with it. I'll never go back to mechanical shifting. Now the braking test to me was a wash and should have been declared a draw because the difference was only inches. Thanks for sharing this comparison David!

It could be confirmation bias but the winner SRAM is the one I’d have backed based on the separate reviews. In fact, I’d made up my mind for my final choice next bike to be SRAM equipped. This side-by-side video was the exact video to back that up. Thanks

Really enjoyed this video. I slowly stopped using Di2 and EPS over the last few years because I found AXS much easier to live with. More time riding les time doing everything else. If you have these bikes for a while, it would be great to hear your perspective how they are in a few months or even a year. How much maintenance are they needing? What does braking performance look like then? Are they still roughly equal? Has wear affected front or rear shifting performance? Are your initial impressions still holding?

I just ordered a complete SRAM Force AXS Disc groupset, for less than the new 105 Di2. Shimano is pricing its products at a premium, because they are popular, but I don't think it's worth it. SRAM FTW for me.

Good all-in-all review! I think the rival is now the groupset of the people given all the factors listed but specifically the price and gearing range. Also interesting how Shimano does not even come close to Sram when it comes to mtb.

As an old school racer from the 1970s, while i love the innovation today equipment and kit costs just boggle my mind. I bought a used specialized roubaix carbon 2011 in 2019 … by the time i got it the way i like it cost Cdn $1500. Nicer than my 1970 Cinelli B with fully Campy and shifters on the downtubes. It would be fine with me to still ride a good steel or aluminum frame with downtube shifters. I do enjoy the shimano ultegra shifters a lot more, but i would not lose sleep over them ( unless i were a racer). In the days of ancient history we used tubular tires… expensive, way more flats, but fast and easy to change. Now i have 700x25 beaded tires on 21 mm rims ( 2 sets). Some tires pop right on easily and perfect. My fast tires the continental gps 5000 for some reason are a bugger to seat properly. I have tried several of them… lots of up and down wobbles unless mounted with soap and water. Hardly ideal for changing a flat on the road…in fact i usually carry a spare clunker tire just in case. I guess the solution is disc thru axle TUBELESS with sealant. Now i just need to win the lottery to pay for it all. The reality is cycling was barely affordable in the 1970s for a junior rider in a middle class family….tell me what middle class family can splash out $5 or $10k for a kid’s bike and related stuff… ps i bought almost all of my own stuff. Thanks for reading

Another point to Sram is they include a clutch on their road mechs (mechanical on Rival and Fluid on Force and Red). This makes more viable conversions to 1 X and gravel bikes!

Recently bought my first SRAM AXS bike. LOVE IT.

Very thorough!

Great content thanks, how would campag chorus compare to these?

David Arthur with the hot take on SRAM vs Shimano. Going to ruffle some feathers with this comparison. But, I happen to agree with your points on almost all accounts. Great review!

I choose scram rival for my new bike. The reasons were it's easy to go to a one by and you can mix and match. When Shimano launched 105di2 with no rim brake option and only 2 granny cassettes I was out. It's sad I had to go to disc brakes, but I don't think they slow me down

Never have had an SRAM bike until these year, a Rival one. Shimano bikes since before Shimano 600 which became Ultegra, there were even "Shimano 600 Ultegra" parts for a while. Had 105, Ultegra 6000, Ultegra 8000. What I liked the most about SRAM was the wireless thing and the interchangeable batteries, specially me that I even forget to charge my phone. I have been close to running out of battery for the rear and just swapped batteries between the front and the rear, I do very few front shifts specially with 10/36 and 46/33. Shimano mechanical in my case is flawless and maintenance free never needed big adjustments only a click or two on the barrels. In the MTB I have snapped a couple of cables but on the road bike almost maintenance free including the rim brakes. SRAM some difficulty when shifting from 10 t0 11 sprocket that is not perfect even with microadjust. And in a few months I have had to replace brake pads, disks are much more maintenance demanding than rim brakes. With rim brakes I have gone years with the same brake pads not the same with discs both MTB and road.

Great video. A very comprehensive comparison. I thought it would be a bit closer call than it was, but hard to dispute your points. I have Ultegra Di2 and SRAM Force AXS bikes and I like both systems. My general view is SRAM is more innovative and offers greater flexibility, but I find the Di2 shifting performance and feel is smoother and seems a bit faster to me. My main complaint about Shimano is how it tries to limit your ability to mix and match components whereas SRAM almost encourages it. The one factor that you didn’t discuss is warranty/customer service/durability. I’ve never had any issue with any Shimano component that I have owned, but I have heard SRAM’s quality control isn’t quite as good.

What Scott Bike is that in the video? I love the paint on it.

Thanks David for this comparison, just what i wanted to see! It's kind of hard to believe how hard Shimano dropped the ball with their 105 Di2 groupset, compared to their main competitor which has had their product on market for over a year already. I expected them to be on-par price wise at least.

Now the biggest question is i want a sram rival fd and rd. For my tt bike which has 55-39 chain rings. Will sram rival program be compatible or is it only compatible for smaller chainrings?

Love the video. Although i would like to know more about the braking modulation. The comparison results for braking power seems abit unfair since the tcr with enve wheels and tyres are at least a kilo lighter than the orro. I think both are similar enough in outright brake power but modulation is traditionally better with sram so i would be interested to hear you opinion

Please test the 105 Di2 11-36 on the Ultegra R8100. We need this to work in order to get anywhere close to the SRAM's low gear.

Great review as usual, David! Btw, do you have battery longevity comparison for both the groupsets? Thx

6.46 Correct that you CANT easily update the crankset on the new 105 di2 with 4iii power meter???

I went with SRAM about four years ago because the first bike I ever rode with electronic shifting was Shimano. It was a rental in CA and I rode it in the mountains. When I was really bonked, I kept hitting the wrong buttons as they were just too close together for my fat fingers combined with my no longer fully functional brain. Granted, muscle memory of owning the groupset may take care of that, but it made the decision for me to buy SRAM even though I've been a Shimano diehard since about 1990. The two button for electronic just makes more sense to me.

Hi David. Did you missed out the usage hours & charging time which is quite crucial??

I don’t think they are that far apart, in fact I think it comes down to personal needs. I’m about to build a bike with axs rival because of the gear options and the small saving but I think both options are a solid value for money option for recreational/ amateur cyclist like myself!

Is the Shimano switchable to 1X configuration? I've a Canyon Grail with the AXS with only one 40T chainring (10-44 in the back)... the good thing is that It's up to me to buy a 2X chainring and a front derailleur and switch the entire configuration to 2X without loosing any component I already have. In my opinion this is very important.

What about Stamina of chains, cassettes and so on? What about reliabilty oft el. System? How long do batteries last? What about sparepart prices and availability?

Older Shimano Di2 groupsets I Can adjust shifting offset on the fly with a button on splitter box . for example When I crash or change wheelset with different cassete , can I adjust shift offset on any of new groupsets without iphone app?

is there an eTap AXS Version for a rim brake setup?

Can we mix parts between?

great review. If poss AXS vs Grx would be fab :)

Does SRAM still have issues with break pistons hanging and a tiny gap between brake pads and rotors?

Nothing to compare to yet as I just ordered a Cannondale Supersix EVO with eTap Rival. I have nothing against Shimano but have been riding SRAM for nearly 15 years or better. Started out with Shimano and was okay with no complaints. I like the intuitiveness of SRAM over Shimano but time will tell with me going to two things since riding a 12 year old road bike with mech drivetrain.......1) Disc brakes; 2) electronic shifting. Only one is truly wireless from my understanding and that is SRAM. But I could ride either I am sure and be just fine. That said........great video and explanation my friend! I love your videos!

Nice take David this one was very expected... do we have one of this about SRAM Rival e Tap AXS against a Shimano GRX Di2? ... and then how about a GRX hybrid to a 105 Di2 ... I see this can could and is maybe happening for up coming bikes a gravel bike GRX /105 Di2 ... did you spot any? can you find one? build one? test one? cheers. keep delivering.

Just got Sram Rival on my allied echo.... and I'm loving it!

I'm being straight with you. Sometimes I have a bit of a dig and I can be a bit sarcastic but overall I really do enjoy your channel and I appreciate the work that you put in. At nearly 70 years of age I'm no racer but I do appreciate the vids. Especially enjoy the sportive/audax/ road rather than racing bikes. Thanks again.

You didn't mentioned that Di2 doesn't work on Karoo Hammerhead because of "private" ANT+ protocol (and god knows what they're going to do in the future about other manufacturers) whereas Sram uses "normal" ANT+ which works for everyone. So another advantage for Sram.

It would be good to have the same comparison for Sram Force and Shimano Ultegra Di2 12 Speed. Searching on youtube I could only find one in Indonesian, I think, or one done 2 years ago when the 12sp Di2 was not available.

David - just a quick point on the braking; an aero bike like the orro will always stop slower than a climbing bike, seeing as it has less aero resistance and usually more weight; it seems unfair to compare the 2 braking systems on 2 vastly different frames.

Took a spin on a bike I was interested in yesterday and one of my takeaways was I am not interested in Di2. The buttons were horrible! I could barely tell which is which, I can't imagine what that will be like when I'm wearing thick gloves! I really wanted to like it for the longer battery life and using an HG freehub, but it was a solid no. I just want a good modern bike with mechanical shifting.

Is dot fluid still the only option for sram brakes? Dot fluid leak on carbon frame is not fun.

I'm with you David on each category those would be my exact choices. I find SRAM better for having low noise under braking and more clearance so less pinging. I don't know about the new 105 my GRX brakes ping a lot when riding just riding through a puddle. GRX feels a lot more powerful than Force. Nothing is perfect and I'd take the SRAM all day long over Shimano.

Aren't 10 cogs super inefficient for speed tho? Or why did they use to make groupsets with like 13-14 smallest cogs in the standard crank years? I have an ultegra 6600 equipped bike and the limit literally can't be set to work well with an 11-28 so I have a 13-30 which works somewhat well although the 30 is slightly rubbing when powering uphill (stock rear was like a 14-25 I think but I'm waay top weak for that)

My new bike (Specialized Aethos) has the Rival AXS, and I really like its intuitive shifting system. That said, I find the front shifting (upon which you did not comment) has an annoying lag. I actually have to initiate the shift a couple of seconds before when I actually want it to happen. I’ve also found that I need to use the “ micro-adjust” feature for the rear mech more frequently than I’d like. I do, however, really like the gearing options available on the SRAM.

Gear selection (not weight) should be the number one factor in group selection for amateur cyclist...For SRAM to offer a 30 chainring and a 36 cassette combination seals the deal for any cyclist who would consider climbing..

Couple of thoughts (I don't own an electronic groupset) - 1- do the replacement parts cost the same (I thought Rival was much more)? I'm on my third rear (mechanical) derailleur. 2- is it possible with Sram to move the chain between front derailleur chainrings at almost the same time as a rear derailleur shift? I do that often, Ultegra mechanical, but can't see how it can be as quick with having to push the Sram paddle twice.

David, I wonder how cheaply we could upgrade an existing bike to Scram Rivel eTap. I have a Synapse with ultega mechanical and hydrolic disc brakes. I assuming the disc brake calipers would be ok to keep as would my absolute black oval chainrings. So could I buy just the front and rear mech, rear cassette, chain & shifters or an I missing something?

What is the name of the bike with the rival ?

Great comparison. Thanks. I also missed modulation of the brakes. I hear that Shimano disc brakes are a little bit better (less brake rub) but the disc rotors of Shimano are worse. I wonder if disc rotors are a point of improvement because rotors are often too light and easily distorted by heat (leading to brake rubbing). I am very pleased with my Sram Red and Force AXS bikes. I like the system a lot. I expect that the hood shape of Rival will be introduced to Red and Force in the future and that would be great. I do think the 10 gear is a bit of a miss. I would rather have a 18 in stead of a 10. I hope that Sram will bring better cassettes with 11, 12, 13, 14, 15, 17, 19, 21, 24, 27, 30, 33. or 11, 12, 13, 14, 15, 16, 17, 19, 21, 24, 27, 30 or 12, 13, 14, 15, 16,17, 19, 21, 24, 26, 28, 30. Just my two cents.

How performance of the brakes can be compared if they are installed on two different bikes?

I like the single paddle for shifting and the left side shifting down and the right up for the Sram much better. I also like being able to bring the batteries inside to charge in the winter. New bike cost with SRAM does seem to be more though on average.

I found your analysis to be more objective, David. I noted a lot of measurable metrics involved in your commentary. And while I do love SRAM, I have spoken to multiple eTap users who have complained of ongoing front mech issues. At least at the SRAM Force level. Because of that; I have shied away from SRAM and have gravitated much more towards Shimano relative to electronic groupsets. I wonder; have you had any performance or functional issues with your front SRAM mech? Have you heard any similar complaints regarding its overall quality? As always, thank you for your excellent content 🙂

Great review. Rival for me.

Something no one seems to be talking about is the total cost of ownership. SRAM cassetts and chains look expensive. Their system also looks incompatible with most third party parts. From what I have seen SRAM has a better app and easier setup however.

Is it easy for the front chain to fall off in a slam?

I switched from mechanical 105 R7000 to SRAM eTap AXS (mix of Force and Rival parts). I had high hopes for 105 Di2 but they let me down with price, gearing options and no power meter. I hope at the very least, Shimano expands gearing options for Ultegra and 105 because SRAM is eating their lunch.

I have an S-Works Atheos frame with Sram Force group set with a power meter that I never knew I needed till got one. Right now the bike is around 6.8 kgs if I take or a few bits off, Garmin mount a tiny rear Blinky lite. I had Sram Force on my Specialized SL6 Tarmac, it's easy you set it to sequential and go plus it keeps you in the big ring longer and if I make space on my bike computer screen it'll show which gear I'm in. I'm a 66 year old retired Boilermaker if I can figure out the app it's pretty easy.

In the 12 years of having Sram cycling products on my bicycles I've had two catastrophic failures. In the 47 years of using Shimano products I've had minor annoyances and no failures. The good thing about having competing products is how the quality improves faster.

Same tires for he braking test?

Strange that the test does not cover battery life. A Shimano battery last as least 4 times longer than a Sram. Also mechanical noise from the drivechain is a nightmare from most Sram products. I have use a long time to trim and optimize the mech on my wifes Sram Force. There is also a quite log delay on Sram, from the time you shift on the leaver to the mechs are moving. A extra feature that 105 doe's not have but who is on Ultegra and DuraAce, is the buttons on top of the shifters, allowing you to f.ex. change screen on your computer without taking your hands from the bar.

I want to love the new 105 so much, but I just cant.... I prefer to ride 52/36 cranks with a 11-28 or 11-30 cassette and for me the groupo is also too heavy. I hope there will be a new Tiagra to take the place of the 105 for my Specialized Allez Sprint built.

What bike is this on the right?

I feel the braking distance test isn't done fairly because the group set are not mounted on the same bicycle frame. Different bicycle frame have different riding characteristic. To me at least if you want to do a fair comparison, everything right down to the wheel set has to be equal. But nevertheless I know it is not always possible because the bikes could be yours and you're not sponsored. But thanks for taking time to do these comparison review.

Shifting speed. Did you go into the software and change shift speed to fastest for the shimano??

Sram Rival is the winner for me. Love the improved gear options but don't like the extra 200 grams. To compensate a bit I'd use a lighter cassette like the Force cassette 10-33. Even with a little more expensive cassette is still going to be cheaper than the Shimano group set.

Personally I would go Rival with a Red crankset. Get the lightweight bling crank, save money on the rest and still have a lighter/cheaper groupset than Force.

Can we have a mechanical 105 VS GRX comparison next?

I've just ordered a Dolan with 105 Di2, I've not ridden a bike with electric shifting so I'm just looking forward to embracing the change from 12 year old 105!

Converted from Shimano to SRAM about 18 months ago. SRAM hands down. Gearing and ride alone make it a clear winner. Much more range on the ride. Better climbing and more speed on flats. Plus he is quite correct in the video that shifting is in fact intuitive for SRAM. Shimano is still a great option and produces great products.

So, is Campy Chorus now the 12-spd groupset "of the people"?

This video was sooooo wanted! At least for me...In the past have owned an 105 and Ultegra SL then did the leap to SRAM Red 10sp (all mechanical/rim versions). Shifting and braking were a nightmare on Shimano and things got all the way better with Red with their Double Tap system - except the front mech (meh!). If you had a top mechanic to find its hot spot, all OK. A race groupset, mean and fast. After 10~11 years I decided to change my custom bike with a complete bike. Customization these days is an esoteric sport... So disc brakes + electronic groupset was of high importance. I decided to follow the SRAM path as shifting is a no brainer...so intuitive and flawless. And since Red & Force prices were so steep, Rival was a solution... Glad that Shimano did a (semi-) electronic 105 but something inside me told me that SRAM was still a winner. Heavy? - Yes!, Expensive? - Yes! But with more personality (each SRAM groupset differs from the other), compatibility/upgradability (common batteries, motors, software, mix & match whatever you want), speed (top editors from Cycling Tips & Bicycling + some videos in UKposts show that Rival is faster AND quieter than Red & Force!!! - And you David proved that clearly wins new 105) and finally GEARS. My God ! I am pedaling 40 years now and in the age of 55 a dream come true!...These ratios are for the everyday rider, easy on the mountains, ultrafast on descends. Sorry for this long post, honestly this David makes so good videos and feel good to write down some thoughts . The video is short but so juicy and true. Everything you want, nothing you won't. Believe that David, once again, you really deserve a 'like' and our subscription. Have all a great weekend and happy trails!
