Important note here as a cycling physio myself: You can definetly make changes to the bike to fit you better BUT you can also work on your body to fit the bike better. Flexibility/mobility and core muscle endurance are really important factors for a successful bikefit. Also unless the fit is competely off, small differences won´t be a deal breaker; the human body is adaptable and can deal with variations as long as they aren´t absurd. Trust your body and give it time to adjust before any drastic changes.

I agree, as my core got stronger and I got more flexible, I did changes to my bike fit for more aero positions, particularly to improve comfort on the drops. My pedaling technique also changed which required me to bring saddle to a more forward position and/or tilted down to keep my butt from being shoved backward against the seat.

As a short person, easily the biggest improvements in comfort on the bike have been 1) smaller handlebar width and 2) shorter crank length. It seems that so many stock bikes come with the same bar width and crank length from XXS Frames to Medium frames, despite the fact that the riders will have significantly different bodies.

I would argue that a 80mm stem on a small or x-small is just one size down from the design size for that frame and therefore a total reasonable bike fitting adjustment.

About eight years ago I had a professional bike fit with Garry Kirk. I went to Garry with lots of pains - neck, shoulders, wrists, lower back, knees, pins and needles in my feet. After a few hours, buying a new saddle, narrower bar and shorter stem, some other adjustments I was pain free. I could cycle for hours in drops without any pain. I was able to generate more power - FTP “increased” by 80W!!! Last year when considering a new bike I went to see Garry again as my needs and mobility changed. The bike I got is a size 56 cm. ALL manufacturers recommend a 54cm frame with the dimensions they ask for. But none checks how flexible you are, what your goal is, arm length and more. I have a bike that suits me perfectly. I said it many times to my club mates that money spent on bike fit was the best bike related investment ever.

I've said this before on previous bike fit videos but the biggest problem is the bike manufacturers themselves. The recommended size for a lot of people based on height and/or inseam is generally wrong and the bike will then also be supplied with the wrong size stem, handlebars and crank to match some arbitrary average figure. I would never buy another bike off the shelf now as I have to replace so many parts it just makes more sense to buy the right size frame from the start and build it up from there.
@ronitdebnath Рік тому
I reference a 525 (520-530) effective top tube or so. I never go off sizing charts. Because not all of them recommend the same sized (in terms of objective metrics like stack reach seat tube angle) bike for the same height, so what is that worth even?

@dblissmn 10 місяців тому
I started off with my current bike in 2007 with a 90mm stem, inverted. I'm glad the bike shop did this, because subsequent improvements in lower back flexibility despite some degeneration that was spotted on MRI have left me with a 110mm stem the right way up in combination with slightly greater seat height.

Can highly recommend James Thomas in Richmond - just a legend in bike fitting. Excellent videos on Cade Media too. But manufacturers are at fault here.

@lukewalker1051 Рік тому
Phil's fit philosophy is spot on...and will summarize what I believe based upon several decades of riding.... - Narrower handlebars are generally more comfortable and faster and yes handlebar width affects reach. Larger bikes....I ride a XL...generally come with too wide a handlebar. - For an aging road cyclist even with longer legs...I am Si's size...shorter cranks are better on multiple levels from hip impingement to pelvis angle on the saddle and ability to rotate the torso down and ride more aero. - Frame size is NOT necessarily tied to body size. I am Si's size and I ride 1 frame size up for more comfort versus more aero. Lance who is 5'9 ish raced on a 58cm frame throughout his career and Si at 6'1" rides a 56. - Endurance geometry...what Phil said again, works best for the 'average' rider and not ex-pros like Si. Pros were pros for a reason. Pros throughout their riding career, rode out of the wind with less steep torso angle than most mortals can tolerate. I could ride Si's bike maybe even without a saddle adjustment but after 20 miles my body would hurt because I am older and less flexible, and I am fit.

The simplest solution is to see a bikefitter with a fitting machine. You come up with an ideal position and then check the geometry charts to see which models and sizes match best according to frame stack and reach as well as standover. I see it in about 50% off my fits where riders are on the wrong machine for their body type and ability.

Bike vendors are certainly complicating things for cyclists with the trend towards the integrated/proprietary bar & stem combinations.

I was limited to stem choices exclusively from the vendor or to go with an integrated bar/stem combo, again, exclusively from the vendor (and very expensive). Great video!

As a relatively new cyclist, cycling solo. It’s always been hard to tell if my fit is good, bad or anything in between. It can be hard to justify a bike fit if you are new to cycling because it’s a decent investment you might think is spent better elsewhere. I’ve never felt a bike has fitted me great, but I used myvelofit recently and done it at home on my turbo and I thought I was starting from a “decent” position and it changed me massively. I feel much better now but I was always moving my saddle lower and lower and my bars up and up and this done the total opposite, saddle up by almost 50mm which seems nuts! But it just worked. I’d have never got to that position myself

I'm 60 years old now. Back in 2017 I bought the last 2015 Masi Gran Coursa on the showroom floor at Chainwheel Drive bicycle shop in Clearwater Florida. At the top of the down tube is a sticker that says 59. I test rode the bike 3 times over a month, thinking it was perhaps a bit short along the top tube. The price was so great that I bought it anyway. I set the seat back a little bit and as I've ridden it, I've come to the conclusion that it's pretty much perfect for me. I've never been close to professional as a cyclist, this is the first 'go-fast' bike I've ever owned. My goal when shopping for such a bike was to get one worthy of, at least, a Shimano 105 set, and thats what this one came with. The rims it came with were Mercury and at the 11th month on a 12 month warranty those rims were cracking, and the spokes were pulling through. Masi were very kind to replace the wheels with DT Swiss 460s and they are awesome. Much stiffer and definitely stronger. I don't know how I could be happier with this purchase. I absolutely love it 😀. I just wish I had this bike when I was 19. A nearly $1400 bike for $800 with a Shimano 105 set and a bike thats definitely worthy, in my humble opinion. MAYBE one day I upgraded to Ultegra. But I'm not really trying to eek out a couple more mph without sponsorship 🤣 Excellent bike. I dont really blame Masi or Murcury for the first pair of wheels. They had fewer spokes and were probably more for a few races than to go as many miles as I did. The DT Swiss are very nice 👌, strong and stiff. At about 6 feet tall and ~200 lbs this bike is great 👍. FUN times and fitness control 😀 Oh by the way with the 52 tooth chain ring my record top speed is 48mph 😃. I tried like heck to get 50mph but my legs can't pedal any faster and maybe a 54 tooth chain ring would be a bit much for an / this amateur 🤔 😅 Great 👍 vid. Thanks for the post.
@justcheckinm8 Рік тому
I had a 52cm Merida Ride 4000, picked based on height and some other basic measurements. I had no end of problems with numb hands and 'other bits' and after a fitting check at my LBS, shorter stem, seat slid forward, etc, it was determined I have longer leg:upper body ratio. I replaced it with a 50 cm and was waaay better. It was a PITA when I bought a Trek Emonda SL7 because it has a limit on how high the seat tube can go on the integrated post...which required buying the longer seat tube. Never looked back.

That's cool, if I may second that, from Italy but after a good few years in the Uk back then, I ride a now legendary 'cousin' to the Diverge, the AWOL, and it feels like sliding on a sofa, but sliding quite fast for a steel workhorse that is. I was working in a seaside town on the Riviera and l got a second cheaper bike, loving British ones I got shipped a very typical tourer, a Roux Etape 150. Very similar geometries but one is 61cm, the latter is 58. I adjusted stem and bar sizes, it's so interesting how (little though) each bike feels. Both awesome in their own way.

@bikeman123 Рік тому
Not surprising. A combination of the psychology of each bike fitter wanting to make a change to show they've done something for their money and the fact that everyone has different levels of flexibility so what works for one won't work for another. Bike fits are a bit like new bits of kit, no one ever admits to wasting their money. There's plenty of information out there so there's not much you can't do yourself.

@beltonhogue Рік тому
@@bikeman123 Man. You said that perfect. This has also been my opinion. It has taken me exactly 1 year since I started riding to get my fit to where I am happy today. I could have paid for a fit, but for me, I wanted to learn how to do my own fit. I see it as part of the learning process of the bike in general, and not about saving money. Throughout the entire year, my fit changed because my body kept changing from riding. Can you imagine how many fits I would had to have? Now that my body is better prepared, I won't be doing anymore adjustments! One more note....sometimes articles have the correct Information. I read somewhere that for a person 5'11, that is the only height that has a suggested known crank length, which is 172.5mm. I wanted to try 165's (to see about opening up the hip) which were good, until I tried to ride out of the saddle on a super steep hill. I went back to 172.5, and raised the seat to compensate. So I say when looking at Information, really examine the source, which is another problem with finding a bike fitter. How many really know exactly what they are doing, and your body tells you what Is right or wrong anyway by experimenting, being careful not to injure yourself while doing so.

I'm normally proportioned and I got myself two sizes smaller frame and I still end up using the shortest stem available!🤣But I wouldn't want to get smaller frame as I'll lose the ability to put two normal sized bottles in the frame triangle. I actually ended up loving the short (32mm) DH MTB stem on a road bike for a lot of reasons. The top of my drop bar is only 40mm lower than the saddle. May not seem aero but it allows me to ride in the drops comfortably most of the time. And if I put my hands on the hoods or ramps, I can sit in a nearly upright posture, which is safer than riding hands off to stretch your back during a very long ride. Love my unconventional road fit. It's fast, agile, and comfortable even in non-stop centuries (if you didn't have to stop to pee).

I'm in between L and XL. I'm 6'1" with long legs. Currently, I ride a 58cm road bike, a 20.5" Mountain bike. My road bike fit seems fine but I could probably make a 56cm work. The mountain bike fit is more challenging. I have a Surly Karate Monkey with 27" wheels and a Scott Scale 970 with 29" wheels. Both are XL/20" frame sizes. I don't have as much top tube clearance as I'd like--less than 1/2 inch--but the L/18" frame size felt too bunched up and I'd have to raise the seatpost almost to max to get my leg extended. I guess I could've put a longer stem on but the XL/20" fits fine minus the lack of clearance

@beltonhogue Рік тому
Something I learned of value....know your saddle. Some saddles (SELLE SMP Triathalon) are designed in a way that the back of the saddle is raised to where it looks as if it is higher than the front due to the padding in the back, but is designed that way so that when you sit your bones on it, you sit evenly, and the cut-out relieves pressure and has a short and curved nose for rolling your hips forward dropping down into the drops. When off of the bike, the nose looks like it is angled upwards, which is the correct way with this saddle. You will find this out because if you position it using a leveler on the saddle back edge to front tip, your body wants to slide forward because of the back end padding! So you have to angle it a little upwards.

I would highly recommend a first-time buyer research geometry and their fit before walking into a LBS to buy (or going online.) A first-time buyer is likely to buy from a shop they can try out bikes. This can be a problem for two reasons: 1) their newness to riding means flexibility hasn't been developed and 2) unless they are a median size the bike shop will try to unload what they have instead of the correct size. From my survey of my LBS I find short people like me, are likely to be sold a bike larger than they need. They stock nothing smaller than medium frames and have lots of large and XLs. When I bought my first race bike long ago, the dealer had medium, 54" frames and tried to convince me that was my size even though I had reservations after sitting on it. I ended up bringing it back a few days later and forcing them to source me a 50" (this was back when seat tube length was the measure and comparable between bikes.)

Think again. The wear on the bar tape in that spot comes from the hand rotation involved in shifting gears and the type of glove you wear. Some gloves (Assos) have aggressive dots on the contact points which tend to wear the bar tape when hands are rotated while still in contact with the tops of the bars - ie: Shifting, especially mechanical shifting.

Very right. My legs are proportionally much too long in relation to my torso. I had to get a bigger frame (caad12) with a top tube that was too long for my reach. I swapped the standard stem for a 60 mm, together with a more narrow handlebar and this solved the issue. In contrast to what many people say, I have no steering issues whatsoever, the bike is not too nervous.
@ashleyhouse9690 Рік тому
@Jan Willem Kullenburg - I'm in the same position as you but according to the bit fit I have had you have gone down completely the wrong route. You need a smaller frame with a shorter top tube to match your shorter upper body. Longer legs are accommodated by longer seat post. Although you assert otherwise a 60mm stem is way too short. I agree with Phil Burt that if you need shorter than 90mm then you are on too big a frame.

Great video! I have a long torso and shorter inseam for my height (6 ft) so I am often in between sizes. I need a much longer reach and tend to run a pretty long stem (120mm). I recently used a bike for calculator for an Enve Melee that said I should buy a 56 when I usually ride a 54. What bike geometry measurements will impact me most or how should I view the differences of reach, top tube and stack height to optimize my fit? I’m worried a 56 will feel too big but that a 54 will not give me the reach necessary to feel comfortable

20 years ago my bike fit was very different from today. And some massage or a chiropractor may change many a sore back and neck. Allways I bring tools to adjust sadle. And there is one fit that is right for head wind, another for wind from behind, climbing a.s.o.. - riding alone or social, racing or zone2. Where do I spend the most time. It will always be a compromise, I think

@norsangkelsang7939 7 місяців тому
I find moving my cleats back and forth will affect the stem length and saddle fore and aft. I think this is overlooked many of the times when considering position. Very few times in the past 40 years have had it dialed in. And when I change shoes... that magic is lost. Have a dynamic system where all the variable can be manipulated real time would be a precious joule. And then get the item to replicate that geometry.
@MatthewLenton Рік тому
I'm tall and bought a large bike on both the recommendation of Raleigh and the bike shop I bought it from online, but it was just too big. The main problem was that I couldn't even touch the floor with my toes when on the saddle, which was at the lowest level. The handlebars were too far away, and while I could've adjusted those if that was the only issue, the saddle height made it unrideable I then had to go through the rigmarole of packing it back up, sending it back, and waiting for the medium to be shipped. That was a lot better and I probably need to raise the saddle a little as it's just a touch too low. I've not had the chance to ride it yet

When no one talked about these things, in the late 80s, early 90s, there was a guy in Miami, Nelson Diaz, who talked about high cadence for climbing. When Lance Armstrong started to climb at 90+ rpm, Nelson told me: he's still missing something: his crank length is too long, which makes the circumference longer and the efficiency lower. With shorter crank length you reduce the time during the pedal stroke when the power applied is meaningless, on the top and on the bottom. Nelson experimented with crank lengths down to 152 mm.

@dorianblue4229 11 місяців тому
Hi, some 5 years ago I bought two bikes in short succession and they were my first decent bikes ever. I'll just mention them here cos they, ehm, 'fit' in your video only partially. One is a graveller (but sort of allaround), Speccy AWOL, size XL/61cm. The other one, for rougher use in town, a classic British tourer, a Roux Etape 150 size 58 (the largest of the three they made). Superrelaxing travel bikes, but also smooth rolling and apt for 150+ km day rides. 1) At times you want to push hard and go fast on them too - so i would love to hear if Phil's considerations apply to gravel bikes as well (he just mentions them here, but I wonder whether he's just really dismiss them as broadly usually good and that'all?) 2) about stems and bars, (am 6'2", 36" inseam) there's one more problem: some heights fit between two sizes on the producers lists. I'm mostly listed as top large of a "large", and first entry of the "XL" sizes too. Which is always bit confusing. I've tried and ditched a few stems before being happy, which was bit frustrating... just by myself, i had to... i can now say i've ridden both for whole days in these 5 years, so it's ok i suppose... however, for various reasons i fit two of those superwide gravel bars which is are so trendy lately... a Funn -G-wide 50 cm on the Roux, and a Walmer bar 60 cm (75 in the drops, lol) on the AWOL. My ahoulders are 46ish cm wide. I fitted a supershort, inverted (-5°) stem with the Walmer.Yeah bit less aero (but not much, of all factors) but i have no pain after rides ajd love the control it gives. It's like a flat bar too in its own way (so wide)... Going to the Alpine winding roads, I don't think I'd feel so safe and in control with the stock 46 bars. And this way (arms spread) they allow me to open my lungs and breathe so deep and easy... Well, it's be cool what Phil (awesome guy, of course) might say about this all... cheers!!

The problem for me as a short rider is that most small road bikes come with 170mm cranks and 40 cm bars. My gravel bike came with 165mm cranks and 38 cm bars. Same frame size and manufacturer as my road bike. The gravel bike fits me way better and I feel I get a lot more power through the pedals. Of course the geometry is different, but still.
@marksIItimewarps Рік тому
They probably ran out of stock on shorter cranks. I also prefer shorter cranks. While calculators tell me I should get 170mm crank and I have average leg proportions, my highest average speeds, unbeatable PRs, and one KOM was all done on a 150mm crank on a kid's bike. It's hard to find these, especially if you're on a tight budget looking for cheaper options. I found a few cheap 150mm cranks made for kid's bikes but unsure if they can be installed on an adult gravel bike.

As someone who sits right in between 54 and 56cm, I go for a 54cm with a couple of spacers under the stem and a little more seat post out.

I've gotten so I don't even bother looking at frame sizes anymore. I just look for a frame with a 73 degree seat angle, and a 58cm top tube length (or virtual length) If it has those numbers, I'll know that it will fit, when built up. One of the frames that I ride is listed as a 55.5cm frame (with a severe sloping top tube) another is a size 59cm. Both fit equally well. One thing I learned, the hard way, four decades ago, is to not adjust your reach by moving your saddle back and forth, on the rails.

@anthonyduncalf6190 Рік тому
I'm 168cm in height and some size charts say I'm size Small and others say XS or even XXS. I have ridden all sizes and Size Small was the worst as the reach was too long even with a short stem. So you can easily get the wrong size bike by following some bike manufacturers size charts. XS and XXS bikes do have stems shorter than 90mm though and it's perfectly normal. One thing that doesn't get smaller on smaller frames is the wheel size so there's only so small they can make a frame due to toe overlap so a short stem is needed to get the right reach. A 80mm stem on a size Small or bigger bike shows there's something wrong though with the fit.
