How Much Difference Does Handlebar Width Actually Make?

Рік тому

Should you swap out your bike handlebars to something narrower? Over the last few years, there has been a trend in pro cycling to more compact riding positions using narrow handlebar set-ups. The claims are that it’s more aero and therefore faster, but how much so? Ollie wind tunnel tested three different bar widths to find out how much difference it really makes!

How wide are your handlebars? Let us know in the comments below! 👇

@gangstermonke1 Рік тому

I ride 36 but I’m only 14

@Dejay1788 Рік тому

38CM because my shoulders are very narrow.

@Numeriwar Рік тому

40cm. Just enough space for climbing and its also my shoulder width . Anything wider feels like driving a truck

@evigvandrare Рік тому

I ride with curve's 55cm walmer bars, which flare out even more on the drops. I have super broad shoulders so the narrower bars that are standard are really uncomfortable for me.

@ariffau Рік тому

32cm centre to centre. For context, my shoulders measure to be 41. My bike fitter told me to run 38. But I still feel 38 is like steering a bus 🚌

@russstarke6004 Рік тому

@dainiusvysniauskas2049 Рік тому

It's best to choose handlebars with bike fit in mind. With that said, 38-40cm bars tend to be the sweet spot from what I've heard.

@n22pdf Рік тому

Good advice I used to ride 42 as that’s what I had a few years back.. then I went for a bike fit and was told I needed max of 40 but a 38 would be ideal, switched mine out and wow what a great improvement for me.. but may not be what everyone needs same as crank length etc 👍🤩🏅

@brianrainey2739 Рік тому

To me, this just confirms that comfort and leverage is more important than aero when choosing your bar width. Also remember that many pro riders have narrow shoulders that may not be what you see when you look in the mirror.

@KarlosEPM Рік тому

I agree

@jeremynorth Рік тому

I agree completely also narrow bars just look crap

@tobycolin6271 Рік тому

This test is only relevant for a rider with the same width shoulders as Ollie. If your shoulders are wider than you can run wider bars with no penalty. All this test shows us there is an optimal width for ollies shoulders. So for ollie yes a 380mm bar is optimal but gforca larger rider it might be a 400 or 440. So without ollies shoulder width it’s doesn’t apply to others.

@graemeblundell2884 Рік тому

I also agree. Bar width = shoulder width for comfort.

@huntos83 Рік тому

Comfort is most important absolutely, leverage really is not. When you are moving on a road bike you need very little leverage to control the bike, steering is done mostly by shifting your weight and not by leverage turning the bars, you do not turn the bars into a turn you lean into it to steer. The situation on a mountain bike is very different where you may be moving very slowly at times navigating tricky terrain, and then your point about leverage is much more valid.

@hansschotterradler3772 Рік тому

I recently swapped my bar from 44cm to 42cm. I'm noticeably faster now. Not sure if all that training and losing 9 lbs have anything to do with it. No, no, it must be the narrower bar.

@nickporter3531 Рік тому

My gravel bikes run 42 at the hoods /54 at the f drops and road 42 at the drops and 39.5 at the hoods. Comfortable ride is 1st priority for me as I am older and a bit out of condition (chubby) at the mo! If I was racing then I may consider narrow bars, but not really an issue for my normal riding

@rob-c. Рік тому

44cm is likely too wide for your shoulders anyway. The 42cm is likely to be closer to your best position comfort wise, which would have more effect on your times than the minimal aerodynamic advantage.

@miket2646 Рік тому

@@rob-c. Very good point here. Comfy = Fast

@whaleshark2625 Рік тому

Love my 44cm bars. I have fairly broad shoulders and feel very crunched up on anything narrower.

@roblucchetti2993 Рік тому

As others have commented here, and I have experienced for myself generally, any benefit I have had from downsizing bars has been due to A) better handling feel, B) shorter overall reach; yes, when you widen bars, you increase your reach to the hoods C) less stress on my hands and elbows from being at incorrect angles.

@Dejay1788 Рік тому

Surely choosing handlebars based on bike fit, rather than marginal aero gains would be the best course of action for most riders.

@serdiezv Рік тому

Narrower than your shoulders is almost always ok, wider usually isn't

@TechSucht Рік тому

@@serdiezv true, but most people measure their shoulders wrong. Muscles don't count one must measure the shoulder bones. As a result a lot of people are using handlebars which are too wide.

@serdiezv Рік тому

@@TechSucht and you should also measure with a relaxed stance or the measure goes a bit wide too. When you put your hands on the handlebar your shoulders roll slightly forward and thus go a bit narrower.

@-P-Z- Рік тому

I'm on 42cm at the moment. Was contemplating to go for a narrower ones. With this data this would make no sense to me. My AVG speed is far from 45kmph hence expected gain would be even more minuscule. Thanks for this insights Ollie.

@andreasolsson2336 11 місяців тому

wind speed.

@DEAR7340 Рік тому

8:15 - Exactly what my perceptions were. 1) elbows were in line with the knees 2) upper arms were closer to the ribs, smoothing out airflow 3) shortened the reach (slightly) and made things less of a stretch. I thought that the wider bars would open things up for easier breathing and alternative hand positions, but this hasn't been the case - - for me.

@faw6979 Рік тому

It would be interesting to see this test done in the aero hoods position.

@michaelwood5897 Рік тому

The measurements savings would still be the same. You need to look at the aero hoods position and add that measurement on top of the bar width adjustments.

@nicknameunavailable809 Рік тому

Interesting information and appreciate how you discuss various aspects of the topic. But must be cool getting to ride surrounded by fans! 😁

@mischief2168 Рік тому

Love you too. 😊 I switched to 38s. That's my shoulder width so more ergo-gnomes are made happy. I feel a little safer in traffic being narrower. Downside is a bit less real estate for bells, lights and whistles. Worth noting different brands measure bar width differently so potential for confusion. Maybe gains would be bigger for those of us using round section bars? Thanks for the content - good stuff.

@ShawnIsBatman Рік тому

I believe that the most important component of handlebar selection should be proper fit and comfort derived from a proper bike fit. Once you have the fit reference, don't go wider than you need to for the optimal aero benefit for your situation.

@serdiezv Рік тому

I changed from 42 to 38/40 (hoods/drops) and couldn't be happier, I'm even thinking about getting the Enve Aero to go 35/40

@emilvaradi9393 25 днів тому

Bar width is also important for comfortable wrist positioning and can be perhaps a more important reason to have narrower bars matching your shoulder size.

@mpvsystems9302 Рік тому

I purchased some 38 cm wide relatively inexpensive aero road bars last season to see for myself. Having ridden on 44 cm wide bars (42s would have been a better fit for my shoulder width) for over 40 years, I definitely noticed the difference. Feather's point is well taken as I found climbing out of the saddle on the 38s provides less leverage and took a lot of getting used to. However, with the hoods angled in on the 38s, I am able to gets my arms in line with my legs, and the reduction in drag is noticeable. I would estimate, the 38s are 1 - 2 kms faster above 40. I would be very interested in seeing the wind tunnel data for this position. The adjustable width bar seems like a great idea as it allows riders to adjust their setup depending on the route. Great content!

@galenkehler Рік тому

Traditional shoulder fitting always put me on a 42, but I tried a 36 on the track about 10 years ago and found it to be more stable and easier to hold the black line at speed. A counterintuitive result, but I switched all my bikes to 36 and never looked back. It's more comfortable since you aren't reaching sideways, and keeps the bike in better alignment when sprinting. The outside of my knuckles are the same width (~42cm) as my hips so it keeps a nice aero profile too which is a nice bonus.

@philippang07 Рік тому

I'm 6ft and ride with a 42-110mm bar-stem. Lovely vid as always from Ollie and team. Thank you so much for great content. Tempted to try 40mm, which I did for a short spin, with a 120mm, and it felt perfectly fine and comfortable. But I hadn't tried this combo for a long ride. So, inconclusive for me, will speak to my bike fitter. Quick thought after watching the vid was, if the speed / time gains are marginal, and we're not racing competitively, fit and comfort are key over narrower bars for the sake of being just a tad more aero. Position on the bike, cycling wear including socks, and shoes, all add to the aero advantage but as a recreational enthusiast for gran fondos, don't think it makes that much of a difference. Quite another thing to be racing competitively.

@kelvinhandley3392 Рік тому

Great video Ollie. I run 42s but didn't realise how small the different was. Could GCN do an experiment on a fast loop to see whether it's quicker to have a cross-wind there and back, or with a headwind there/tailwind back? Try it with box section and deep section wheels for a constant power output?

@davidcawthorne2942 Рік тому

I ride 43cm bars as this is around my shoulder width and works for me. Confirmed in a bike fit.. Anything narrower and it's not as comfy. Personal preference I feel. One thing I drew from the vid is how narrow ollies shoulders actually are. Love these kind of vids by the way.

@ariffau Рік тому

Running a lot narrower bars make you sit higher up. Hence, it is recommended you also increase your stem length to maintain the same numbers yet still get the advantages of running narrower bars. Btw, I run 32 bar centre to centre.

@ariffau Рік тому

Before anybody disagrees, please feel free to consult aerocoach about this 😄

@ghowell13 Рік тому

Love you too , Ollie, and thanks for the vid. Would like more like these, but always enjoy the shows. Bike fit is something I struggle with. Constantly. I'm reticent to change anything once I've gotten where I like it. I'm also only recently into road cycling, say 5 years, but wasa MTB, and BMX cycling my whole life. Bike fit has come a long way since the early 80s.... I run 44s currently, as its close to my shoulder width. I've tried several bars during what my wife calls "the dark years" of my starting cycling, nearly 2 years of fiddling with my used 11 Madone to make it fit me. Bars bigger was like a bus. Smaller, and my back and shoulders would ache, as you pointed out. I suffer from years of chronic back pain/ back injuries, so I'm very sensitive to any changes to my bike, or me. I would try various bars for about a week, and as soon as I'd go back to the shoulder width bars, with 2 days of riding, my body would settle down again. Of course, everyones else's s'mileage will vary. Take care everyone, and keep the shiny side up! (Unless it's intentional)😂❤

40cm on my 10 year old road bike. But this was after my bike was stripped for parts, when left locked up in London, shortly after I got it. (handlebars removed for the shifters). When the bike shop, thankfully on an insurance payout, replaced the parts the mechanic picked 40cm rather than the original 42cm, as he felt if fitted my body size better. He was right, it felt so much more comfortable. Perhaps just get a size that matches your shoulder width.

@traversecitysufferclub Рік тому

Should have been aero hoods position. The riders that started the narrow bar trend are turning their hoods in. The narrower hood position facilitates a position where the rider's forearms can be hidden from the wind, hands close together, and hands close to the rider's face. Testing narrower bars, but having the rider on the drops might not show the difference being felt by riders in the "aero hoods" position.

I had a bike fit recently. My 51cm Orca came with 40cm bars. The fit suggests that for comfort and efficiency for me, 38cm are right. So these are on order. Most manufacturers do seem to fit bars that are wider needs in general. I’ll see how I get on.

My Orbea M30 has 52cm flare bars. My Trek Checkpoint has 48cm flare. And my Trek Domane has 47cm flare. I even put 48cm flare bars on my indoor spinning bike. I'm 5'11" 230lb, 60 years old. Even though I have so many years of riding on and off road, my bike handling skills just need the width. A professional bike fitter would likely fire me and not allow me back to their office, but I do not seem to have any issues with pain running such wide bars. I think the flare makes it so. If I were to try running a standard bar at 52cm, I probably could'nt. Thank you for making this video and sharing the info. Though I do not race, and so aerodynamics mean little to me, I do enjoy learning and gaining new knowledge.

@emmabird9745 Рік тому

Hi Ollie. First of all more please. Love this sort of thing. It would be interesting to know the width of your shoulders (as you're the test specimen). There are both interference factors and frontal area factors in play here. Area is obvious but the air which comes in between your arms has to pass through the "ducts" between arms and body so closer arms is less air air squeezed out the side. These are, therefore, relative figures and may be less obvious for incredible hulks and more so for bean poles. You mention that you got shoulder pain with 36s so I would guess your shoulders at 39-40ish. My bike came with 40s and for years I rode it with accomanying shoulder /neck pain eventually. About 12-15 years ago I switched to 36s to match my narrower shoulders and the shoulder/neck issues are much reduced. Balance was impacted originally but I got used to it pretty quick and it is only now an issue if I'm climbing steep and slow and I'm exhausted too. Oh and they were too narrow for the "spinachi bars". Which brings me to the other factor that doesn't show in your examples (ok you say things aren't all aero). If you're doing a long ride, the pain in the neck and shoulders is likely to cost lots more time than aero can give you so getting the right width for your body might be more important. Incidentally for the 10TT as your shot of Si shows, you'll be using the skis anyway and you blast off the front in the last 10 comes after a lot of kms anyway. Still, as I said, more geekiness please.

@iMajeala Рік тому

I’ve tested different ends of the spectrum with 42cm down to 35 (Enve SES Aero). 42cm is wider than my stance and never felt good. 40 is very neutral and allows me to maintain leverage in a sprint. As I go down to 38 and 35cm, the sprinting angle tucks my elbows in considerably more. Some power may be lost, but it maintains a more aero position. Climbing on narrower bars is something you have to get used to as well.

@marcgranadogonzalez1987 Рік тому

Very nice! It would be interesting to know the whats you are saving though! As in, in order to get the same time in the 10 miles TT how many whats would we be saving with the 39 cm compared to the 43 cm given the 43 cm is riding at 230 W?

@davemoss6976 Рік тому

In a TT you would have tri bars or TT bar set up, . For a breakaway in a road race, you could/would adopt a narrow body position by holding the bars towards the centre , ok for the short time that it really matters. So in the real world, the stats suggest you should choose bars for comfort and handling not aerodynamics.

@ThetrueAP Рік тому

Oli! Like you, I love experimenting. I have moved from 44 to flared 38/42 noticeable different but my curiosity became focused on tops vs drops and found that on the 44/44 the drops were usually 2KPH faster on a flat road but when switching to 38/42 and keeping low on the hoods I found no difference in tempo speed. Traditionally hoods have been more comfortable so could in theory the correct flared bar be the answer to comfort and handling at a consist aero speed?

@huntos83 Рік тому

I am 6’2” and usually ride a 58cm bike, and they always come from manufacturers with 44cm bars fitted which feel absolutely massive and ruins the handling of the bike, it feels like driving a bus. My preference is for 38-40cm wide bars and I find this transforms the handling of the bike and makes it feel much more nimble, while also being much more comfortable for me. Also narrowing the bars can make quite a big reduction in reach. Yes there are some aero benefits to narrower bars but for me the improvement in the feel of the bike is a bigger reason to change. There is an assumption by manufacturers that taller riders will have wider shoulders and need wider bars, but for the most part this simply isn’t true - while some people are tall and broad many taller people have slim builds without wide shoulders and often actually shorter people are broader and more solidly built.

I've start my cycling in XC, when 560/580mm flat bars was a standard. I was one of the first to move to 635mm/15mm raizer Easton EC90SL bar, and everyone was talking that it's so wide. Now we have 750-800mm bars on XC bikes xD On a road bike I always stay with this shoulders to bar ratio, which for me is 420mm. I'm pretty sure that all gains on areo that I will get by having narrower bar, will be compensated by capability on wider bar to be faster in corners etc. And I'm not against aero, cause I have a lot aero equipment(Canyon Ultimate CFR eTap with 50mm DT Swiss ARC1100), but I believe that there should be a balance between aero and other stuff ;)

@nathanhaney91 Рік тому

Unless you're a very large person, 44cm bars are not a good idea for the road. When I first asked about bar width at my local club, one gentleman (a former USA Cat1 racer no less) asked me, "What's your suit jacket size?" I told him it was a 42 regular. He said, "Then you're probably around a 42cm bar. Suits are measured in cm at the shoulder...make sense?" Learned two new things that day lol.

Narrow bars reduce the reach on the bike , so your body is likely become more upright, you will have to keep the reach consistent to make the test meaningful.

@chickenpoodle Рік тому

no, narrower bars do not reduce reach on the bike. straight arms provided by properly fitted bars reduce reach on the bike. the moment your arms have to swivel outwards or inwards because the bars are too narrow, or too wide, is when you are increasing reach. the only reason why we always hear that it seems to reduce the reach, is because most of the time manufacturers spec bars that are too wide for their consumer base.

@Cyclingchoice Рік тому

@@chickenpoodle in the experiment when the bar is set up to the widest the rider will have to lean forward to grab them, when the bar is set to narrowest the rider doesn't have to lean forward as much, my question is what is the impact of the riders position in term of aero gain or loss?

@tidalwavestudio Рік тому

I switched from the original 44cm to 40cm wide because of comfort. It removed my sore neck immediately... If too wide, you tend to roll in your wrists to match the width of your shoulders and thus cause a cramped shoulder/neck situation causing neck/shoulder problems. For non-racing bikers, that maybe more important than a bit of aero gain ;)

I’ve gone from 40cm bars to 34cm. Mainly because I’ve always thought my arms were short and I kept getting neck/shoulder pain but after watching a bike fit video where the fitter suggested measuring between the acromion I found I just have really narrow shoulders (31cm at 180cm height). Once I switched to the 34cm bars (31cm at the hoods as they are turned in) I needed a longer stem and could remove some spacers. Bike looks like a proper racer now and I’m a lot faster on my normal routes. Handling unaffected but comfort has gone through the roof! I’d suggest more people measure their shoulders and compare to bar width if they are having shoulder/neck issues.

Tried every bar width from 32-44… settled on 36 (180cm tall).

A few years ago, I watched a documentary about Sir Chris Hoy, in which has been said that if in the wind tunnel engineers where saying he was faster using a 36cm handlebar, he would have trained (night and day) to adapt his position to it. I believe if you are competing on a track, you can do that (with a lot of training and sacrifices), but if you are "racing" on a road (especially at the Etape du Tour), it would ve better to have a bike with a handling suitable for your riding skills. I heard a lot of stories about accidents in that "sportive", especially going downhill. A narrow handlebar on the bike of an inexperienced cyclist could be one of the reason. Before being faster, be safe and go home in one piece.

@williamtaylor6818 Рік тому

Would be great to see this data maybe on a track bike going up from 30cm all the way 44cm

@mohamadjamil3164 Рік тому

Am changing my handlebars to a narrower one to for a bike fit and handling reasons and not aero gains. I believe that you can go faster if you are more comfortable

Next time, just throw some wider tape along the top/bottom of the bar to cover that gap you talked about. Would be very similar to bar tape and would eliminate some penalty seen in the wider times.

@CristianoVicente Рік тому

I've chosen the bar width my bike fitter told me to get, 42cm and it causes me no pain or discomfort so I do prioritize that over marginal aero gains.

@cb6866 Рік тому

Thanks Ollie and crew...OAF and SAF...comfort is key , to me . I would think too narrow is uncomfortable and unsafe ?

@calebgonsalves2970 Рік тому

try it, made the jump from 40 to 36mm bars and was squeamish at first (was originally going to go 38 but no dice on a cheap bar) more comfortable than ever and definitely far more slippery

@dainiusvysniauskas2049 Рік тому

Depends on your body - handlebars that are too wide is one of the most common cause for neck and shoulder pain.

@cb6866 Рік тому

@@dainiusvysniauskas2049 True. I’d do a bike fit before , but I didn’t know that when I bought mine ! Got lucky

@matthewbaynham6286 Рік тому

I don't race anymore, my TT days were over twenty years ago. Now I'm middle aged, overweight, with high blood pressure, so aerodynamics isn't important to me. I like 44cm bars for comfort on a racing bike, but at the moment I only use a racing bike on the turbo and I have flat bars for outside (after I've finally gotten around to fixing that bike).

@adambrickley1119 Рік тому

Would be really interesting to do a video on exactly how you generate the data in a wind tunnel.

@Aeronwor Рік тому

On the 41cm bars you can see Ollies wrists rolling inwards, a clear sign that the bars are too wide.

@robinvandenberg25 Місяць тому

I have quite narrow shoulders and my bike comes stock with 42mm wide bars. I will try 38mm and see how it goes, 42mm feels quite wide for me.

@ildigergelysteinbach2380 Рік тому

Interesting video. Thx Oli, but as aero nerd, I find you should tape this upper chanel of the handlebar to eliminate there not optimal aero behaviour as in the real life this section is wrapped (as you mentioned) 🤔

@oliverbridgewood3929 Рік тому

yep! we were on a really tight schedule!

@brankododig1585 Рік тому

36 for me, although fit wise I could go with 38-39 without any issue. Everything wider feels wrong. Even on my gravel bike 36 is perfectly fine for handling.

@alexanderpolta Рік тому

MTB vs Gravel vs Road vs Track makes obvious that the longer you go, the less width you need to feel comfortable. As narrow as is comfortable is the answer.

@Servicevelo Рік тому

I’m 193cm 90kg and use 38’s. I have for years. The gains are purely in my head I know but I also shave my kegs for the same reason which is……. If you want to go fast, you need to feel fast.

Do you have the CdA for the 3 widths?

@antonrichter5032 Рік тому

How much does the ever lengthening groove on top of the bars affect the drag as you widen the bars? Surely it creates turbulence around the edges of the groove.

@dovy6666 7 місяців тому

what cm is the narrowest setup?

@matteodiluce9387 10 місяців тому

The stated time gains are the result of complex simulations. Did those factor in the maybe not so ideal mechanics of climbing with a narrow handle bar (as mentioned towards the end of the video)? I'm sure a narrow handle bar makes perfect sens in flat terrain, but much less in the hills or mountains.
