Emma's Bike Fit | Saddle Position, Handlebar Setup & Pedalling Technique

Despite Emma's years of experience at the highest level of professional cycling, she has surprisingly never had a bike fit! Our long term partners Shimano invited us to their high-tech bike fitting facility in Maastricht to see how they conduct one.

In association with Shimano.
Like many of us, Emma has always set her bike up using rules of thumb, and what sort of feels right on the bike. But these days bike fits have evolved from this, Shimano's involves a number of different steps and even some motion capture cameras!
The upshot of this though is that bike fits can ensure that your position on the bike is perfect, and allows you to get the most enjoyment out of your riding.

[@DudeThisHappened2Me]

As a short (157cm), female cyclist you can't even begin to understand how much I appreciate this! Thank you

[@Desi365]

you have to go for teenager-sized hybrids/ MTB. My tip.

[@DudeThisHappened2Me]

Desi I don't enjoy hybrids or MTB so it's not really a tip tbh. Emma is the same height as me and she's a roadie champion. I meant it was helpful in understanding how to make my bike more comfortable as it's not hard to find a women's bike for my size

[@JS-tb9hu]

It’s good that the industry is added smaller sized bikes such as canyon

[@gcn]

Cheers Kim, glad you found the video useful!

[@emmapooley433]

Kim hi Kim I’m glad this is helpful - I know how frustrating it can be to try to find a bike to fit as a person our size! I do recommend trying 650b or 650c wheel size road bikes.

[@geoffbaker4452]

Considering this exposes Emma to public scrutiny in terms of her slight physical imperfections ( who is perfect after all?) I think its very brave of her to do this. She couldn't do it without such a good sense of humour. For a former pro I find Emma very down to earth and easy to relate to.

[@stephentuthill4598]

Geoff Baker Emma shows that in taking on athletic endurance event you don't have to be perfect.

[@richardcarr6493]

l wonder how much she improved her performance.

[@herbertmasing]

Well said! I don't know anything about the pro-athlete world, but 5 mm of difference in leg length is nothing for ordinary people. This is a very very common thing and I guess if the phd doctor found this so surprising, it must be a big deal specifically in the top tier athletes pool..

[@aaron___6014]

Why is it brave? Pros are human too.

[@zedatomic8342]

We love Emma! An accomplished pro with not a hint of arrogance - a natural and engaging commentary that fits with amateur bike riders and bike nerds alike! A really great addition to the GCN team. Keep the videos coming Emma!

[@andybrown141]

Yes bike fit totally got rid of back pain and changed how I ride . Went from 172.5 mm cranks to 165 mm , narrower handle bars , and totally different seat . Totally worth every penny I spent .

[@conanshing778]

That moment when Emma is putting out your FTP during a bike fit 😭😭

[@petinka721]

I understand why Emma did this. The most important competition is near and it is not about money. It is about pride and I will keep my thumbs for you Emma! I want you do a thing for me Emma. win! Emma win!

[@gcn]

Haha, cheers Petinka!

[@bobmarengo8322]

All the people on this video’s comments area that are virtually screaming at Emma to eschew this bad quasi-medical advice are correct. Emma is getting very bad advice from this center/guy. Bad podiatric, bad osteopathic, and bad medical advice in general. I hope she gets her back/hips issue addressed, as it is extremely obvious when she walks or rides that she needs proper rehab and appliances to allow her to then adjust the bike to optimize her position. It is all too common for some of these types of centers to try to treat injuries and related disfunction by skewing the bike to force her body into compensatory misalignment/realignment. He is not even addressing, or noticing, her real problem- and is instead, incorrectly asserting that her 4mm leg length differential is unusually large- and is the cause of her issues. 4mm, which he claims is big (although impossible to measure accurately the way he does it)is actually very small (lower 10%), as most women average around 0.4” (about 10.5mm). The AAOS, and many sports med research centers and peer-reviewed research is in dramatic conflict with both his measurement approach, and his recommendation based on a supposed 4mm result. He is wrong by almost a factor of 10- even if he could accurately measure the way he is doing it (you can’t, as any good osteopath or chiropractor who is not trying to scare-up business will tell you). He is incorrectly compensating for her injury-related auto-compensation, which is indicative of a problem that needs to be addressed prior to any fine tuning bike adjustments. Gross bike adjustments used to compensate unilaterally for physical injury induced or related disfunction is bad medicine. That is what sportothotics and other appliances and therapy are for, and are often combined with specifically designed rehab programs for optimal post-injury recovery. Otherwise, he is setting her up for a dramatically shortened biking career filled with unnecessary pain and significantly increased likelihood of surgeries that could have been avoided. He will just be adding stress to her hips and knee - and very likely other elements along her kinesthetic chain. Very bad advice, but not atypical from a center specializing in selling a single solution set, rather than practicing sports medicine plus offering a broader range of sub-specialties.

[@sodalitia]

Interesting point you make. If her leg length difference was indeed significant, wouldn't she need some kind of orthopedic inserts or differential shoe hight for riding a bike? If his measurement of the leg length was correct, by increasing the seat hight he is simply forcing her to put more strain on the hip of the shorter leg and cause more rocking of the hips side to side. She was already quite capable of adopting areo position with the previous saddle hight, why increase it? Also at 9:45 he talks about high value of the "knee extension" and when she says its "to flexed" he agrees. WTF? If he meant "knee forward of foot" value - that would make sense. But when you say "knee extension" its the one in red and when her foot is down. To me her leg is even too much extended, so increasing the seat post hight makes this value even worse. Why didn't he bring her back on the sensor machine after adjustment has been made to see improvements? Why he is not talking about stem length and tilt, frame geometry? Like those are unimportant? What about her clinical history? Did he even bother to look the X-rays of her sacrum fracture pre- and post surgery? It all looks quite sketchy to me.

[@sodalitia]

So called "broader point" is just a nutjob's excuse to molest people with their paranoid convictions, while contributing zero to the actual discussion. Get off the videos about cycling and internet altoghether and get a job with ANTIFA. Surely you won't profit from it so it would be plain right for you commie.

[@johnratcliffe6438]

Emma needs to see Dr Rahim, a Gonsted practioner. He'll sort her out.

[@ToCGambler]

A bikefit was key to get me back into cycling. Started off last year and got injured on my left knee during a sportive. Had issues with my knee for 6 months and couldn't ride further than 10 kms without pain. Orthos even wanted to operate my left knee, but once I got the bikefit done and I was provided with insoles against pronation of my left foot, I was able to return to my usual 250 km/week immediately. So anyone experiencing pain on the bike definitely should go for this, can't stress how thankful I am.

[@gcn]

That's pretty remarkable! Glad you got it done.

[@omnambiar1765]

ToCGambler I’m sorry and I I understand the pain you went through as I have been through similar things, but you sound like a dodgy American infomercial

[@ToCGambler]

Lol yeah. Usually I'm not the person to advertise for something.. But in this case I hesitated way too long because of the high price that is associated with it, so that's directed towards those that are hesitating as well and are facing the same issues as I did. I'm so positive about this because this was pretty much like a magic trick, for my condition that is at least, and I wanted to share that. Next time I'll ask the company that did it for money in exchange lol

[@brillowolf]

This video needs a post fit review to get Emma’s opinion on the outcome of the fit.

[@kiwim3p587]

There is something about Emma, a high class person

[@gcn]

Cheers Darren!

[@senna1rossi]

Such a great video. Informative and scientific. Thanks GCN, and Emma! Just brilliant...

[@gcn]

Cheers Senna, glad you enjoyed it. Check out the Geek Edition for a closer look on GCN Tech too!

[@unitedgray]

One of the best GCN videos I've seen yet. I've never had a professional bike fit, but this is really enticing me to do so. I would have liked to see more of the exact "corrections: that were made to Emma's bike after the fit. Maybe her thoughts after a decent ride post-adjustment as well.

[@JS-tb9hu]

Same

[@edbrown7422]

My bike fit was the best money I've ever spent on my bike. Noticed a positive difference immediately. I'd definitely recommend.

[@gcn]

Cheers unitedgray, you can check out the more geeky edition here - gcntech.co/bikefitgeek

[@mikemowett7401]

The sensors that showed how much force is where on the pedals, was amazing technology.. The whole process starting at the beginning with checking the riders anatomy etc. was thorough. I had no idea so much was involved for a bike fit. Thank you for a great video.

[@liammcgough9969]

I thought that I was going to learn about just bike fitting from this video.But, I really learned about how to be humble from Emma as well. She really did a great job.

[@dominicsarmen]

Was waiting for something like this, as a small rider myself this helps thanks 👌🏼

[@gcn]

Dominic Sarmen glad to hear it!

[@darienadley5544]

That motion capture fitting set-up is remarkable. I liked how the fit started with the physiological assessment, before going anywhere near the fitting jig.

[@leqin]

Its nice to hear that Emma's set her sights high this year - really looking forward to the Presenters Challange now. Also - thats got to be one of the most amazingly interesting video's GCN's ever made and the geek edition is....

[@gcn]

Glad you liked it Nigel, cheers for the support 👊

[@leqin]

Any chance that Emma can come back to this fit and its results later on after she's acclimatised to the changes it makes, only we get to see other fits but never hear from the person how they feel its effected their cycling long term.

[@jeshely]

We need more of Emma on GCN! Haven’t see her in a while.

[@michawodarkiewicz371]

She has left GCN, sad news indeed.

[@jeshely]

Michał Włodarkiewicz Sad to hear that! Thanks for the update.

[@ojtibi9906]

Win the GCN Presenters' Challenge! Yeah! 🤣🤣🤣

[@triestelondon]

There may be the TdF but the GPC must surely take precedence.

[@gcn]

Stay tuned!

[@davidholland2109]

I've just got a bike fit myself and cycled the island of Arran yesterday and honestly I felt amazing after it. I could of kept going couldn't believe it

[@gcn]

It's amazing what a difference it can make eh?

[@zakswan4644]

I cycled round Arran before it has views that are amazing

[@Hunter_Bidens_Crackpipe_]

Same happened to me, no bike fit, I was on an ebike.

[@imstillhere6678]

David Holland Have, not of. Basics...

[@TheWaxChainFanClub]

Did you visit the Arran Distillery? Lovely.

[@ianwalker8557]

Wow learnt so much in a short video

[@gcn]

Cheers Ian, so did we!

[@roof30]

That was fascinating. As a shorter rider myself I understand the desire to want to shorten your seatpost length to try and maximise power output - and I suffer from ITB issues as a result. This has made me realise that I also need a bikefit, so thanks for the info GCN; very helpful, as always.

[@gcn]

Let us know how you get on with it, will you? Cheers for the support.

[@Megadeth6633]

Shorter seatpost length gives you less power output. Your muscles aren't stretching enough distance thus limiting the potential.

[@Juan0003]

9:26 "I can see already. I'm rocking!" Yes Emma, you rock!!

[@alanwilliams9021]

Excellent and very informative, thank you GCN

[@ronbyers9912]

I recently had a professional bike fit. I can't begin to describe the advantages that accompany a good bike fit. Afterward my power and speed were dramatically enhanced. Surprisingly for me after the lift my bike become far more stable. Don't hesitate to have a professional bike fit.

[@gcn]

Really glad to hear it Ron!

[@eterlizzi]

Love the personality of Emma when he mentions the cables are for people up to 2 meters! Priceless

[@gcn]

😂

[@LegSpinna]

Do UCI rules allow one leg to be longer than the other?

[@fluidefluide1128]

Only if the longer leg length is offset by the number, gender (left or right ) and severity of a road curve .If there is a serious disparity then a lead wieght must be incorporated into the cleat to offset the obvious advantage. It's a bit like having a hamster run round a wheel, if you don't make sure it does runs with the axle on the left or right equaling out eventually it starts to walk in a circle. Hope that clears that up.

[@ChrisAcheson]

Don't quit your day job to be a comedian, donut.

[@geoffreyanderson4719]

>Do UCI rules allow one leg to be longer than the other? Did Eddy Merckx have one leg longer? No? .... no.

[@jbratt]

Only when compensated by sock length 😀

[@adinur1653]

No, they don't. But they do allow one leg to be shorter than the other.

[@richardcarr6493]

very informative video lots of different aspects mentioned here

[@paultheroadcyclist8714]

Great video, Thanks Shimano Tech Centre and obviously Emma for providing us with the insight

[@terbennett]

Excellent video! You really shined with this one Emma. If anyone had their doubts, this video should've erased them. Great job!

[@kakarot2430]

Neil : Any particular objectives that you have for this bike fit? Emma : I really, really want to win GCN presenter challenge. Neil : I can imagine that...who doesn't... lmao

[@Addamo]

Loving Emma. What a wonderful addition to the team and the show.

[@tarmacsurfers]

jeeezzzz that is one hell of bike fit setup, surperb. Great video Emma!

[@gcn]

Cheers tarmacsurfers! Thanks for watching!

[@kissCharles]

something that's very underrated for shorter riders.. the usage of shorter crank

[@andreibarbu3228]

Can't wait for the GCN presenter race

[@matthewlewis2072]

I'm putting the mortgage and the kids' college funds on Emma

[@brandonmusgrove6294]

You know it!!!

[@markmiller4414]

Great video! Really wanna know what Emma thinks of this new position after she's been riding it for a while. Hope to hear something in the future.

[@gcn]

Cheers Mark!

[@patrickhance7348]

This was very informative I think I going to get a bikefit thanks 👍 . Pat from Belgium 🚲👊

[@gcn]

Patrick Hance cheers, let us know how you get on!

[@michaelhackenberger7632]

Patrick Hance juuuu

[@AndrewEbling]

Well done Emma - your delivery keeps getting better. Also glad to see GCN have finally recognised the value of a good bike fit.

[@gcn]

Cheers Andrew, have you had a bike fit?

[@AndrewEbling]

Global Cycling Network I have indeed had a bike fit - at WyndyMilla - although that was more of an old-school session with an experienced fitter who went by eye/experience than computer based. The results were astonishing - I cycled home feeling like I was flying a few feet above the road surface. The fit was so good, the bike kind of almost disappeared - it became part of me. Hence I’m a huge fan of a good bike fit and side with the many people who describe it as “the best money I’ve spent on anything cycling related”.

[@phillwhitlam6999]

Another great video from Emma. Really interesting and explained some of the mysteries of bike fitting. Emma gets more and more relaxed with every video. Keep em coming guys.

[@Skjoldborg8]

So great to get some insight into how much there is to bike fitting! Very very useful, and great fun as well! :-D Thumbs up!

[@NielsHeldens]

WAIT EMMA WAS IN MY AREA AND YOU DIDN’T TELL ME! This will not be forgiven! Also, the bike fitter has an awesome first name. With a name like that you know you have a talented and just all round great guy helping you.

[@gcn]

Haha of course!

[@zippycork5464]

Niels Heldens

[@mariconor242]

This is excellent, really informative stuff.

[@bikndave68]

What a great video and thank you Emma for putting yourself out there. It would be great if within two to four weeks you would revisit this subject and let everyone know if your new position improved your cycling experience. Thanks again!

[@AdamJStoryDC]

Did he shim the shoe or were the other changes enough to make her comfortable?

[@mcone1959]

Thank you for an excellent and helpful video. I have been riding for a couple of years and am still struggling for the correct fit. Now I've finally scheduled a bike fitting with a certified fitter and am looking forward to the advice she will give. This video gets a big thumbs up from me!

[@IdolOracle]

4:33 suggests you might need a "sock fit" - does that say "Right" on your left sock?

[@emmapooley433]

Haha, I must have put my socks on in a bit of a hurry!

[@bobbysilver272]

Most leg length "differences" are cause by a problem in the pelvis angle, not leg length. (Less than 5% have actual leg length differences). The fact she also mentioned breaking her sacrum quite recently could also be the cause of this. Handle the pelvic muscular imbalance and this should get resolved.

[@Vaioman67]

Way to go EMMA! So glad your with the GCN Team!

[@gcn]

Cheers Stephen!

[@sumorich1978]

I rode 50-75 miles per week for around 8 years. Haven't been on the bike in over 4 years. Decided recently to dust off the bike this coming Spring and found GCN videos to entertain and refresh me through the winter. I have no idea why I loved this video as much as I did. This could've been a 2 hour video and I would not have minded.

[@awildtomappeared5925]

I'd love to see a series showing the bike vaults/sheds/attics/graveyards of GCN hosts

[@gcn]

That's a corking idea, thanks!

[@ZeroSeriesMMX]

aWildTomAppeared Ahhhh... We need to raid Jon's attic, especially!

[@gcn]

There's a lot of call for that, somehow...

[@TheBassallyear100]

I'd like it even more if it was possible for the presenters to speak about what bike was their personal favorite ride and why. I expect that sponsors might not prefer that though. I'd also love to see an aero/efficiency/comfort challenge among manufacturers that have aero, all-round and endurance bikes in their arsenal. For example, we've seen Matt's Aeroad pitted against cheap and midrange bikes but it would be great to see Si's Aeroad vs Dan's Ultimate or a Venge ViAS vs an SL6 etc.

[@lr3867]

Emma you are a fighter ! :) please do a follow up on progress after your fit

[@changegeek4553]

Wonderful video for us engineers! Thanks, Emma!

[@sureshchinnappa2290]

Great information. I am going to get a bike fit too😀. Thanks again for showing the benefits Emma.

[@g.fortin3228]

Thats pretty amazing stuff.. I recently just adjusted my saddle height a smidge and was surprised at how just about 3-4 mm made a huge difference in fatigue level ! Love your videos , and the knowledge you share. A+ !

[@acyutanandadas1326]

Same w me. I gotta learn the metric system eg 3-4 mm equals 1 smidge.

[@benjaminzachwieja8133]

I am looking to get a fit this summer. Thanks for the presentation. This was an interesting piece.

[@villamjoe87]

GCN needs more of Emma! MUCH more! :) When I see Emma , I click. That simple.

[@mileysound1212]

Good luck with your goal of winning the GCN presenter challenge. You have the fitness and determination to win. To be absolutely sure of winning, practise telling your left from right, it will help you if there is a navigational element and you will be able to put your GCN socks on the correct way round. Win win!

[@pobg]

I thought ooooh this video will be interesting! And it was waaaaay more Interesting than I expected. Thanks guys.

[@joelioel]

After seeing replays of Emma's performance in ITU Powerman, she's my hero, an absolute beast in the sport of long course duathlon!

[@nickrobinson2023]

This guy knows the anatomy of the cyclist. Amazing skills. Thanks for sharing.

[@g.fortin3228]

Emma did an awesome job here and did herself well to get the bike fit and adjustments made ! I miss Emma on the channel !! A very down to earth and very likable presenter !!

[@squeakygiant]

The leg length discrepancy test is suspect. Typically x-ray and bone measurements are used to determine this. Functional leg length discrepancy could be caused by your rotated hip. I would avoid shimming the shoes to different heights until confirmed. If it is true you are in good company, Eddy Merckx has one too.

[@alainbellemare2168]

totally agree

[@rkitson9436]

My bike fit identified a similar problem and had shims and wedges fitted but they created a tendonitis that meant I couldn't walk for two weeks! Make any adjustments gradually!

[@squeakygiant]

@@rkitson9436 You couldn't walk as you the shimming changed the way tension is balanced in your body. Our bodies are best viewed as tensity objects (similar to a wheel, structural strength comes form tension in this case soft tissue over bones, as opposed to tension in spokes). Shimming changes that distribution of tension, which lead to overuse and tendinitis. I am personally view shimming as a last resort rather than a first step. Often you can develop tight connective tissue through habits (e.g, sitting) that can present as functional issues. In this case slowly releasing the tight connective tissue resets the balance of tension in the body and may resolve these fit issues. Soft-tissue change have to be done very slowly (weeks) so the body can properly adapt. Connective tissues takes much longer to adapt relative muscular adaptation. This is why suddenly jumping into new exercise program can bring tendonitis, as the connective tissue hasn't had time to sufficiently adapt to support the forces in the new exercise.

[@hankg6955]

Emma you put out the most informative videos, cheers!

[@bryant2919]

Fantastic interview, thank you so much for a professional, pleasant and to the point video. Bravo!

[@JN-ow4yc]

As a physio student. Great video to learn!

[@PrinceCbass]

leg length can be caused by spinal misalignment and subluxations. Usually leg length is not in the leg but is imbalances of muscle tension in the neck and spine. Chiropractic adjustments can make huge differences and relieve chronic pain

[@chrizk.9343]

Get into a bind and this thing is a life saver

[@PK-wd1wt]

This was fascinating! Thanks, Emma, for sharing this!

Cheers Jay!

[@VisionElectricAus]

In a world where everyone on the internet loves telling you how good they are ............ I found this refreshing

[@sarastearns8025]

GREAT video! Very, very revealing, thank you, Emma!

[@soundrkappa7763]

Emma also starting saying yep all the time at the end haha

[@66smashy]

This was very interesting. Its always something i'm wondering about. Gonna start by checking the forward/aft of my cleats and the guys recommendation of pedal axle alignment.

[@gcn]

Thanks Simon, let us know how you get on!

[@LomTong]

Oh my God, the colour scheme on that Emonda... Bellissimo!

[@gcn]

👍

[@FrankJackson]

This is awesome. I’m going to find a bike fitting place near me and see how it works.

[@waveandsoundchannel]

Emma, you are an example of person everyone should follow.

[@dannyhanny1191]

Excellent video, Em.

[@AteRed]

This is a really helpful video. I also have a trek emonda and i am 147 cm tall so I wonder what the size of Emma's bike frame is. After watching this video i surely need to make a few adjustments with my saddle height and cleats shoes :)

[@alfonsolizarazo9806]

Every time I get a new bike I comeback to GCNs bike fit videos

[@barrymorgan4826]

I can relate to everything in this video as i am 4 foot 8 (I'm 12) but this video is extremely helpful

[@williamknowles3085]

Finally GCN! A proper video on bike fitting! lol

[@hondasaurusrex6998]

Fantastic video, very informative!

[@KD5XB]

Thanks for this video, it is quite informative and useful.

[@stevecarleton163]

Great Video Emma. coincidentally i just did my bike fit on Saturday (Specialized Retul) and it was very similar to this. I had to get a new wider seat, change the position of my seat and i have new insoles to compensate for the high arches. I was also told my left leg is 4mm longer than my right, which can also be compensated for using cleats. It would be great if you could do a follow up video in 6 weeks time, so you can say how you feel about the new position.

[@dickiedollop]

Thank you Emma you’ve done me service with your video 👍🏻

[@carlblaskowitz7817]

This is what I wanted! Thanks GCN

[@gcn]

You're welcome Carl! What did you find the most interesting?

[@carlblaskowitz7817]

I have been considering a bike fit for myself and was wondering what the process entailed, what parameters might be measured and how precise it is. I'm sure this is a bit more advanced of a fitter than I will find locally but I suspect the fundamentals are the same. I had thought that the process might be a bit of an unnecessary upsell, but the video shows me that it will be of some significant value to increase comfort and to avoid injury. There are other bike fit videos available, but even in a quasi-promotional segment, GCN has earned my trust over some random youtube star promotion.

[@carlblaskowitz7817]

To be clear, I am not a pro or anything more than a health motivated cyclist, but GCNs (and others) content have made me take my cycling fare more seriously than before, adding value to my time on the bike.

[@allthingsTechrelated]

The best bike fitter I’ve seen so far

[@z1522]

Note for small riders: Campy brake hoods make for much shorter reach than Shimano, a cm at least. The concept of adapting to a new position: I felt so strongly that my MTB cleats were too far back that I moved them forward more than a cm the night before a ten-hour marathon off-road ride, then drove six hours home. Age fifty. No aftereffects, and the cleats have stayed in that setup for 15 years since. So much for the concept.

[@MVProfits]

Some, not all, but some of the elements mentioned like muscle tightness, flexibility, etc. can change over time. I get that our bone structure, length, height will not but some other aspects mentioned. Anyway, good to have a bike fit to avoid injuries and simply flow better. But very few places offer that level of adjustments!

[@bunnynikkipeaches2442]

Good Video . I learned alot .

[@jfvanschalkwyk]

Amazing! I need to get a proper bike fit done... have pain and numbness in my hands and wrists

[@steamroller72]

Great video. The science of cycling positioning is very intriguing. Good job Emma!

[@gcn]

Cheers steamroller72, it's super interesting! Check out the geek edition on GCN Tech!

Will be looking for a follow up video on how she adjusts to the new position.....Had a bike fit 10 years ago (and 2+ follow ups since then), and every time I go more comfortable, efficient and faster. Highly recommend spending the money.

What a star. Thanks for doing this.

very nice and interesting use of technology. Like most old heads we went off leg length and plumb line on roller/trainer to dial in. Worked fine for me racing as long as Ema but this type of technology would have been awesome and great to have for the cycling community.

This is cool. I wish there was a bike fitter like this in China!

Fantastic. I'd love to see a follow up video.
