As a professional bikefitter, we have been preaching the gospel of fit first, buy later for decades. I like your selle italia electronic bike but I’m still not quite sure what the AI is doing. I haven’t read all the comments, but did anyone mention that the fitting machine didn’t even have brake hoods! Unless you’re a track cyclist, the primary hand position should be a the hoods/brake levers. The fitting machine should also have telescoping handlebars to determine ideal handlebar width and adjustable crank arm lengths. Ollie also needs a wider stance width on his left foot as I’ve noticed his knee tracks laterally on that side on previous GCN videos. But great that you finally mentioned this concept that riders should fit first and buy second as it does save money in the long run.

@gcntech

Whoop whoop! Another point for bike fits 🙌

I appreciate that for the endurance fit it raised your handlebar without shortening the reach. Most riders can manage sitting a little bit higher without having to scrunch their spinal columns.

Which is exactly why I went to Vires. Every other bike I looked at would’ve needed some adjustment and that’s not cheap these days with one piece bar/stems. Recommended.

Since the bottom bracket is a fixed point you can alter all the other stuffs but you have to keep in mind that they are all levers so even small increase/decrease can make a difference in how the bike feels. A bigger frame with a shorter stem can have, theoretically, the same meseaures of a smaller frame with a longer stem but the riding experience will be different.

I think that the key point is to consider getting a pro bike fit that uses an adjustable bike-emulation machine before buying a bike. Both my wife and I are in the middle of a fitting where the fitter used mechanical device, similar in concept to the one in the video but with manual dials and levers, to dial it to fit our dimensions. He also used devices to measure our sit bones and shoe sizes. So this cost $200 each (was $150 last year), and the conclusion was that we both had bought bikes that were too big. My wife found her entry-level Specialized gravel bike to be too uncomfortable to ride more than 10 miles, but after getting new handle bars, stem, grips, and a seat with proper set up she is now riding without pain. Perhaps investing in a bike fit first could have saved us the extra $400 in new bike parts for her $750 bike. Still waiting on parts for my road bike…

Years ago, I went through a similar process at my local bike fitter before selecting my bike.

The setup involved just a basic looking fit bike and some video motion capture, yet it proved to be effective.

@gcntech

It's great to hear how something very similar worked for you!

I am a heavy rider and because of that, I can't fit like the typical rider. However, that doesn't stop me from riding. I tend to stay away from carbon because most have weight limits that I don't meet, but as far as geometry, what I tend to do is get a bike with an uncut fork, a high rise stem usually somewhere around 17 degrees, as well as putting spacers under the stem. I do not use all in one stem/bars as I am not in that market and I would be better served by loosing 10lbs than spending that kind of $$. Also, depending on the bike, I may also choose a seatpost with some layback. I have also been tinkering with cranks that are a tad shorter than ships with the bikes. I have been opting for 170 or 165 and these help keep my knees out of my stomach which helps a lot. Now, I know I am not your typical cyclist, but if anyone is having these issues you may want to try some of these solutions. The idea of having a long reach with a higher stack height is not new to me, it is something I have been doing for more than a decade now and am very comfortable with.

I wish manufacturers let you pick your components a la carte. I fit a size 58 Trek Domane and had to swap out the handlebars for 40cm ( stock was 44) and am planning on getting shorter cranks eventually ( Stock is 175mm). I should have been able to make those choices at time of purchase, at a minimum with the same component level, possibly same or optional upgrade to a higher level, and then they could assemble my bike.

@izi941

There are many custom builders out there, that are usually also master bike fitters 👌 they will measure you, talk to you about your wishes and needs, and build your wished bike (Domane in your case) so it fits you perfectly (way better than IDMatch and similar system). It will probably also not cost you much more than it.

Doesn’t fit with mass manufacturing efficiency.

I'm nominally a 54 on a bike with more relaxed geometry but I also fit a 56 with a more aggressive geometry. Long torso allows me to adopt a lower position. It would be nice if you could swap out fit components (stem, handlebar width, saddle, crank length) at the time of bike purchase with like components at no extra cost so you aren't forced into buying a bike package that doesn't fit you from the start. It'd save the average consumer money and trouble later on. I'm aware custom builds exist (Trek Project One $$$) but I'd like that option on a workhorse alloy 105 bike.

Great video. I would love to do that bike fit.

The jig not lighting up like a Tron Lightcycle irritated me more than it should! Ending up with some bikes you can actually get and ride is so much better than just being given the measurements and left to figure it out for yourself

I am 186cm, fairly proportioned arms/legs, and 90kg. From where I live, I have no access to such machine whatsoever & probably the cost of such bike-fit is much higher than I would plan to spend in comparison to my bike price budget (btw, was it mentioned how much this session costs, round figure?) so I ordered new bike on-line, based upon the measurements of previous bike and my bike-fit knowledge. So, same as Ollie, the previous was 56 and wanting more comfort (not much interested about high speeds or breaking power records) I choose 57 (Orbea Orca has L on 55, which I could get, for more aero/speed...) so now I find the reach a bit too long, I changed the stem to 1cm shorter. More or less, I got the same result as what the machine got for Ollie. Did I make the right decision? If not, this would be my mistake... !

Very interesting Ollie, always informative. I'm off to Google the price now.

Speaking of sizing... and knowing that GCN works closely with Canyon, I'd really love to see a video on proper sizing with their brand. I find their sizing recommendations really strange. For example, I'm 182cm and set my saddle heigh to 77.5cm. I recently borrowed a friend's large Grizl for about a week of riding in Tuscany and was super comfortable on it... but according to Canyon recommendations I should be on a medium, which I find confusing... and I'm now second guessing myself ;)

Would happily go through this, but for the cost and distance - unless they fancy sponsoring me a visit?! 😁

The handlebar on that expensive fitting rig doesn't have hoods? That seems like a major miss. Most of our riding is done on the hoods.

Being stupidly tall (2.03m), it's surprisingly easy to choose a bike: "I'll just take the biggest bike you have, thanks!" In all seriousness, a lot of manufacturers (cough cough Ribble, cough cough) build really small bikes and XL is only 58cm fitting folk up to 190cm. It's pretty annoying.

Best fit i had was by Pete Matthews (master wheel builder) in the mid to late 80's when buying a new bike from him. He had had a jig built and the methodology was in principle the same, way ahead of his time. Had a few bikes from him, handbuilt and fitted like a Saville Row suit.

I did one of those .. totally off any manual bike fit . Ended up hurting my knee . 6 months of poor knees

I don't have a very expensive bike but if I were to get one I would definitely have a pre-purchase bike fit to give me the right parameters to aim for.

I can never find these wonderful tools in my neck of the woods. Montreal Canada.

I generally always have to change the Stem and Handlebars as they come with a 90 or 100mm stem and I run 120, and handlebars are 42 with a 80 to 90 reach, where I run a 40 and slightly shorter reach between 70 and 75.

My bike shops is small 3 generation family owned, they do have new fancy expensive bikes but also great used ones . But sadly no fitting computer machines, clerk just eyeballs your size he picks a bike and u test ride he adjusts, you ride and you pay when it feels right... Its a chillax place i look for reasons to stop by and browse see which bikes come and go

Nice idea. Then try getting the vendor of the $15,000 bike to adjust the standard stem or crank or… anything at all. Some manufacturer is going to win a lot of market share when they actually focus on the customer and fix that problem.

My bike fitter spent 2 hours assessing fitness, strength, flexibility and asymmetries before I got on the bike, 8ncluding teaching and practising a set of strength and stretching exercises to improve the situation. He also sees bike fit as an evolutionary process and the initial fee includes quarterly return visits to tweak position and exercises as you improve. There's a lot of great use of AI and I'm in the IT business, but it still needs to be in the hands of an experienced human who can assess these things that the AI can't measure.

It'd be great if gcn did a accuracy comparison on online bike fit sites with physical fits like this. Unfortunately, I'm not in 0.0001% of gcn viewers that can afford a 'proper' fit. Having been off the bike for a few years, my old settings were causing serious discomfort. With an extra 4" around the waist and seriously unfit, I found an online site that took my new body size and existing bike then recommended changes. Have to say, it's been pretty accurate. Saved a millennia of time tweaking stuff myself. Not entirely discomfort free, but better by considerable degrees.

It depends on how additional data flows into the machine learning, like flexibility from an anamnese, comfort/discomfort feedback during the fit and afterwards. Plus: The potential of those systems is very high. Minus: But it also could lead to less professional fitting persons standing by these systems.

The big bike makers (eg Canyon, Trek, Spec'd etc) don't help themselves inasmuch as they offer no choice of stem, bar width, crank length etc on a new bike (even though car makers have allowed you to pick options like cody colour, trim colour etc for decades and this info was used to build the car). So because I didn't want to waste money on a new bike to find I had to change out the stem, bars and chainset as soon as I got it (a waste of money and my time), I just bought a good, second hand Colnago frame and built it up myself. But I didn't feel inclined to pay high prices to have to change out the kit I didn't want - the bike brands don't help themselves.

Well it's cheaper thats why they do it. On the other hand you cannot even buy a different cockpit for an canyon ultimate nowadays, they won't offer (I asked myself). Handlebarwidth can be adjusted but no way to change the stem lenght.

I bike hills more often than flat ground. I’d want it at an angle of maybe 30degrees.. near the point where center of gravity makes the rear wheel almost a unicycle.. that’s where I need power, endurance , and balance at the various dimensions. A bigger bike without fixed feet gives you these.

Im 5ft 11.5" & both of if my road bikes are 56cm frames, although one if them has a longer stem, but i dont tend to ride that one on my longer rides, so it suits shorter 1-2 hour blasts around the local lanes.

Don’t bother. Go to a custom builder, he’ll take your measurements, build the bike of your choosing (from frame to every bolt) and after it fit the bike for your needs. It will fit you much better than IDMatch and similar systems (there are many, IDMatch also isn’t a new thing), especially if you have any physical limitations (pain whilst cycling, previous damages to the body etc.)

yeah all well and good. I have some biomechanics training and experience on the bike. My feeling is that automated bike fitting produce weird results because the underlying algorithm is reflecting current point of view in the industry. The "AI" is basically leveraging a bigger database and returning a probable fit, based on many samples. I don't think there is a feedback loop about the long term success of the fit, because people are usually going to a different fitter if thery're not happy. I'm not surprised it suggests a bigger frame. It's acookie cutter approach. No matter how many metrics you're going to capture, if the underlying assumptions are limited, the results will be unsatisfactory. The fitting is done on handleabars without the shifters which bitered me. I know you can adjust for that, but it changes a lot how you interact with the handlebars and the position. Again, not surprised that the system suggested a bigger frame. My fit is optimised for riding on the hoods first and foremost. BTW, I love my Selle Italis SLR boost saddles too. I'm 177 cm and ride road bikes (if you look at traditional geometry) with 53 top tube, 11 cm stem + 7 cm reach bar, zero offset saddle and 165 mm cranks. I also slam my stem, because of my monkey arms. I tried bigger frames, I can ride them okay, but all feel like riding a barn door. Much less agility, weight balance is off, and my position relative to the pedals is less optimal. Whatever bike charts suggest is between 54 or 57, too big.

5Ft10 got a size small Canyon Grizl. Actually, it's a really good fit! Doesn't help being between 2 sizes

57.5 recommended... but 56 can work. What if you want the smaller frame for lighter weight? It would be cool if you could enter optimization parameters, to sort of guide the selected bike based on niche desires.

Opinion from someone who had his bikefitting done with exactly this system, and works in the AI field. It is great, but: - Being AI accuracy is heavily based on the sample size. If only few stores still have them then it will grow quite slowly, undermining the self-improvement factor of the model. Still it can be great and this is the direction the industry should be going - There is an interesting feature that allows you to correct your position based on the pain you are currently feeling on certain areas on a 1-10 scale. On my end, it overcompensated knee pain quite much putting the seatpost so high I could lock the full leg when on the extended part of the movement, making me rock on the sides quite much. My feeling is that it still needs a bit of improvement especially when facing problematics that may not be bike-dependent but health-dependent - The human factor is still important: AI does not substitute the knowledge and experience of an attentive bikefitter. The person not once asked me how the position felt, not even after setting up the bike in the target position. He was actually surprised when I asked "can I try the bike" Bottom line: it is a powerful tool but only in the hands of competent personnel, with full awareness of the underlying model and with a background in sports-science. It's the minimum you can ask when paying €150-200+ for a bike-fit

The sizes come in 2cm jumps but there is enough adjustment on the bike to make it fit you perfectly. I do wish they'd change cranks lengths more though. 165 upto 52's, 170 on 54-56, 172.5 on 58-60 and 175 on 60+. We weren't designed to sit for hours on a bike, so there is actually no 'perfect' size.

My local bike shop does exactly that, although I don't know what tech they use. They start with a bike fit and then can tell you what models they have that would be good for you. I know bike fits make a big difference as in my case it stopped a shoulder and neck issue from being unbearable. Next 'serious' money bike I buy will be after a bike fit.

Curious there are no hoods on the bar to be measured by...which would seem to be a much more normal/popular riding position.

Like a lot of GCN videos, 99% of us don't have access to this fitting technology.

Great to see the xbox one connect still getting used. Crap for gaming, but has/had so many other uses.

Ive beeb looking for a bike fit from Selle Italia but here in the US there are only a few locations. The closes one near me is located in Massachusetts, im in NY, however im pretty much dialed in, my interest was for the right saddle width for the slr boost tm super flow.

Interestingly after my fit I shortened stem and cranks and tweaked position but after some time and subsequent fits I’m back to my original stem albeit in a much lower position.

Great system very interesting 😊 I like Selle saddles very good 😊 Pete

❤ this is good tech ! I really like it! Perhaps it’s not really true AI but what we used to refer to as fuzzy logic? Really helpful though 10/10 😊

This is all well and good, but manufacturers don't allow you to swap parts. You have to make the changes by purchasing wider saddle, longer/shorter stems etc after shelling out for your chosen bike.

I had my bike fit done with Vires Velo and Hayden, went up a bike size too and shorter crank length 😊 then i bought a Factor ostro vam 🤷‍♀️😳🤣🚴🏻‍♂️

The consumer is not the problem but the industry

You've used this machine previously but we still need a list of those machines in Europe.

I love how they've used an xbox kinect for this - truly amazing how we can use technology and innovation for more than its intended purpose.

Did anyone else catch the fact they are using an xbox kinect, 2:00 minutes into the video lol

Probably the cheapest sensor they could get with some 3d photogrammetry capabilities. We use kinect quite a bit when I was doing some robotics work for a certain project.

Would be interesting to see what results the machine gave me. I ride a 65cm canyon with an upwards pointing stem and a saddle height of 952mm. May be worth the £300 to be told it’s only the 64cm roubaix or maybe a 2xl canyon endurace and nothing else.

I’m getting my first bike fit this year for Unbound hopefully I didn’t screw up my bike size and set up too much 😂

Great info Ollie/GCN. It would be interesting to know which bike fitters throughout the UK have this system! There must be more than one? It would also be interesting to know if the Algorithms/Ai can adapt for disabilities? As I recently found out trying to compensate for a disability can lead down a rabbit hole. It's taken me 18 months to find a position that fits. When I buy my next bike I'd like to know beforehand which bike and position suits me best. Thanks guys👍

@@izi941 if you watched the film there was actually a bike fitter there. The thing about the algorithm is (as stated also in the film) the more data it gets the better it can give you advice. And that's all it is, advice! At the end of the day if you want pay for a quality bike fit then go away and change something you can. It's all about finding you a bike from the shelf that will give you a "comfortable" ride. Most of the time people go to bike fitters with the bike they've already bought. As I stated, before I hand over a lot of money for my next bike I'd like to know which one is gonna give me the most comfort. I've been to a bike fitter, how many bike fitters do you think understand my disability and what issues it brings while riding. Basically, the more information I have before I hand over my cash the better. 👍😊

I am finding it hard to know the difference sizes. For example, bike sizing is different from the UK and USA according to many articles. I also have been informed by many conversations and articles that due to the geometry, you need the size down for a TT bike from your road bike. I.e. of you ride a Medium you will require a Small framed TT bike. Please advise me further. Would appreciate GCN answering these questions on the Tech Show. Thanks in advance to all.

Hi, thanks for the comment. We know what you mean with regards to sizing, it can be a confusing task. Fortunately these days most manufacturers have become great with this by giving recommendations on bike size depending on your height. However, there are always some variations and it's not a guarantee that your height, is going to give you the match for a frame size. It's worth looking at the diagrams/geometry charts of the bikes you are interested in, and compare it to your current bike to see which is the closest match. And of course, not forgetting your local bike shop who should be able to help out with regards to fitting and sizes. The TT bike is a good question, in theory if you ride a medium sized road bike, you should ride a medium sized TT bike too.

Creepy! Rather than tech efficiency.

The very sad thing is that most bike manufacturers still sell race bikes with 42cm (and even 44cm) handlebars that you can swap but mostly at a price. The first thing I did was change my handlebar from 42cm to 38cm and throw a perfect bar tape in the bin (It shred in pieces just by removing it). If only bike manufacturers would build to order in the factory or leave the fine tuning to the shops...

@@izi941I don't know. They fit 170mm cranks in small sizes, 175mm in big sizes and 172.5mm in between. This while people either go for 175 mm (the tall ones), the informed ones go for 170mm and the ones who don't know go for 172.5mm. The middle ground in crank length and handlebar width for road racing simply isn't there.

Where are all these system located

i bought a Canyon. they suggested a M. Which i got. I then adjusted all the components to feel comfy. cant be any more difficult than that --also makes sense to raise stack for a longer ride. That what my brain would think. You never said how much it costs to get a bike fit. also id have to throw in airfare from vancouver and hotel.

The stupidity now a days where media influence on people is to get the smallest size frame & put the longest stem, this put a strain on the back & no possibility to raise the handlebar (quill stem was brilliant) coming from an off season & longer than necessary stem makes the bike handle like a dump truck. In the 80’s when I did track we go for the bigger size & no your jewels will not get banged up as you’re riding all the time not climbing down your bike, top tube length was more important than seat tube height. Guest what they still do this fitting on the track & Japan Keirin.

Does the test simulator bike offer different size crank arms for shorter and taller riders?

didn't you guys do this exact video but with Manon last year or something like that? Still a very cool concept. Too bad it's not more widespread and more available.

Ollie did what most people do. Go for a size smaller with a long stem and slam it anyway because it looks cool. 😂

Using the id match locator: Sorry, we couldn't find a store in the area you searched for. Oh, and it's $300

Me and my wife tried idmatch. It’s ok and not as great as you guys keep saying. If there is leg length issue this system is useless.

Or also flexibility, prior injuries/problems, extreme riding styles (either crit/aggressive, or ultramarathon comfy),….I presume? I think it’s more a good sales person alternative rather than to a bike fitter.

Does this mean that the earliest users of this system did not get a proper fit, since the machine had a lot of learning to do?

@ryoukokonpaku1575

For AI models like these you usually feed it initial data likely from paid volunteers with supervision from an actual bike fitter to guide it. After you have enough data it should be ok for customers to use, the only difference really is the initial customers will have a bikefit that's more or less correct while subsequent customers will have more precise adjustments given.

The fit is still overseen by a human bike fitter. And we’re talking about millimeters. You could wear a different pair of shoes or a thicker chamois that would deviate from your “perfect fit” more than the margin for error in iterations of AI learning.

Does this system work for MTBs and gravel bikes? I did notice "ROAD" up on the display.

Froomey was fitted on something similar, remind us how that went.

Does this work for touring bikes where your on the bike all day load carrying huge loads.

@6:26... the endurance riders greatest fear... the exposing of fit problems in the middle of a long ride.

I bought a Trek Domane in 54 cm, and always felt uncomfortable riding it. Swapped to an 80 mm stem, and 170mm cranks and the bike is much better now. The relaxed geometry helps. I purchased a Madone the next year in size 52 cm, and it fits like a dream.

I had the same problem with my previous bike Emonda (2021), size 56. Trek has a similar frame reach to the others, but they use a longer bar reach. In my case it was 100 mm stem + 100 mm bar reach. Others typically use a 100 mm stem with 70-80 mm bars in 56. Buying a Zipp SL70 Aero bars solved my problem perfectly. For the last 2 years they have been using shorter bars on some models.

The topic is bike fitting! Not feeling comfortably without any info about preset values and changes being made. Could be so many variables that leads to you now feeling fine.
