- This was a bike fit that i did recenty for an elite level collegiate cyclist from Spain. In it I share the step by step decision-making process because this client was a great example of why having extremely accurate measurements and making rational decisions of what to change first, and how much, is so important.
The way this bike fit progresses we had to first make a small change, assess the effect before we could zero-in on the proper next steps and end point. Enjoy.
If you have further questions, please post them in the comments and I'll try to answer as many as I can.

This is the best bike fit video I've ever viewed. Well done.
Thank you!
Interestingly, I got an ASMR (calming) effect from watching this video. This guy is the Bob Ross of bike fit advisors 💤 🚴♂️
This is the most educating bundle of info I've come across since I first started a some years ago and stumbled across the late, great Sheldon Brown. I'm a difficult bike fit and while not athletically proportioned, I'm very active. I'm gobbling up all of your videos and they're helping me a TON. Thank you for what you do and taking the time to provide this knowledge to us free of charge.
Steve Johnson Glad to hear, thank you for watching
I'm jus starting out a rookie and I wish I had a fitter around my area as knowledgeable as you feeling uncomfortable and I was fitted really hate to hang the bike up cause there are people out there say they know but not like this , helps me alot to explain to the next fitter what to look for ,thank you
Great video man! Happy to see you didn't just slap on a longer stem in order to stretch him out. I bet he feels nice and balanced as well!
Yep, that's probably what most bike fitters would do, I think, but it's the wrong play. There needs to be a bit more patience in getting to the solution in these scenarios. It also highlights the need for an off-the-bike physical assessment beforehand. can't believe there are still bike fit schools that don't include this as part of their curriculum. Thanks for the support!
I'll echo what others have said about this video being exceptionally good. I got a real education! Thanks!
Daniel Montgomery Thank you!
Wow!!! Thoroughly explained!!! Never realized how much science and data went into a bike fit.
one of the best bike fit videos I have run across. great to see how you work the puzzle. keep these coming!
Thank you!
I've bought a new bike lately and got some knee pains, but also even tho the bike frame is smaller, i felt like i was leaning on the tip of my sadle more.
I'm pretty sure that changing the exact same things as in this video, will help me a lot.
Thanks!
So I did change the sadle. 2 cm lower, 2cm more back and GODDAMNIT!!! It's like it's a complete new bike! It rides 10 times better!
Didn't even need to put the cleads more back.
Thanks a lot!
Been going through a bunch of your videos since they popped up in my suggested last night. Great information, really helpful and interesting stuff. Thanks for all the work you've put into these videos and your blog!
mrk Thank you!
Great video! I specially enjoyed how you explained the importance of making one adjustment at a time. Loved how making one change (cleats) affected another (saddle).
Been following your videos. They're genuine and make a lot of sense. This video probably tops my favorite list. Truly grateful that you spend time to do these videos. Pls keep going!
This is great! I am going for a full bike fit next month. Having many issues with my lower back that aren't helped by my current set up. It's really interesting to see this process broken down!
I have a 2003 Giant TCR 0. What used to be a good fit back when I was younger is no longer a good fit. I shrank a little bit and no longer have the flexibility I once had. Not to mention my knees have worn down a bit and are a little looser in the joints. I don't mean to sound like I'm falling apart because at 53 years old I still kick butt. I did have to purchase a shorter stem and a seat post that would allow me to set my seat lower. I come to realize I had to do this when I went on a long ride with some friends and struggled to keep up towards the end simply because my bike was fighting me. Now I ride that same route and its way easier and faster to do that same course, even though my bike is less "slammed." And I'm finding I'm using my drops a lot more with a bike that is set up for me better.
thanks a million i just relies whats was wrong now i can fix it you know what your doing keep up the good work hopefully we can talk on any points there about thanks again in advance
you are a life saver!!! your knowledge and depth is amazing, thank you for the advice!!!
Yes! Appreciate all you share, and of that being that there are limitations: we may never get fitted to the point where we feel as if we're kicked back in a recliner with a cold one after a couple hours of riding. But yeah, micro adjustments and conditioning can move us in that direction!
One question: why not a longer stem to increase the rider's reach?
joe bolan in this instance based on some of the other measurements I was getting I wanted to try and avoid drawing his body, and therefore his center of mass, forward any further
John, this is a wonderful video. More real-life examples please.
PS I found your comments at 5.16 on the role of the latissimus dorsi very helpful.
Got a retul bike fit paid $275 and my fitter after checking my flexibility found out my left leg was shorter than my right and hip was compromised. Said he didn’t do anything to address the issue with the left leg being shorter because it didn’t show on the system that it was affecting anything. He raised my seat set cleats back some drop my handle bars some the bike felt deferent but in a good way only for my saddle was uncomfortable. I had to bring the nose down a few degrees my self an now it feels awesome.
My fitter didn’t gave me anything to do about my compromised hip I had to research that on my own. Even when I try reaching out to him for advice on what do about my hip I didn’t get an answer. To be honest I don’t feel that my fitter was into making sure that I got the best results from the bike fit. He was more into getting paid instead. At least you showed your client what to do to improve his flexibility on certain parts of his body. Well done sir I would have came to see you instead. Are you in the USA?
Thank you it made a lot of sense I watch your video and make me want to re-consider to get a bike fit it if I have to pay for it no problem but I want to be comfortable on my bike thank you for your comment and thank you for sharing your experience appreciate it thank you lennethmack
Great effort please make more videos on bike fit. Loved it.
Wow I didn't know all of that interfere with the performance. I do fell some pain on the hip sometimes I wonder if this has anything to do with my bike?, since I never got fitted by an expert like yourself. anyways thanks alot!!! I will make an appointment to get fitted so I can enjoy this lovely sport even more.
Interessant hoop dat iemand in Nederland dit zo mooi kan heb volgens mij redelijk de zelfde klachten als deze klant .
Great video. Do you find that your monitor is too high? If I had installed it for you I would have set it about a foot lower on the wall.
+GreaseMonkey X yes, I've thought about setting a second monitor lower. (#436 on the never ending list of To-do's) It's set so that clients can see the screen easier when they're on their bike. My comfort is secondary in this case
this is good, but now i have the problem of buying a thousand dollar ticket to travel to your shop
BlackPaw Sorry about that... ;-)
really interesting and informative vlog
+Lee Crosby thank you!
Excellent!! Love to see more of these!!
Thanks Scott! Working on it. These take a slot of time (particularly because I suck at the video editing :-))
I know this is an old video but here is the question. Is it also possible that the saddle could have been 10-20mm narrower? Or a seat that was more rolled in the back of the seat as not to push him forward. Thanks for all your help. Rick D.
Question: why not use an extension value between 25-30? With a bias near 25. The number and credibility of studies confirming this are compelling. I know Dylan Johnson provides a list of these in his review on the topic of saddle height.
Greetings from Chile
Very interesting video, thank you very much
I wanted to ask about the system you used to measure the pressure on the seat. Where can I find it or read more about it?
Greetings
Excellent vids. Please do one on a mountain bike fit
Very interesting!!! some very small changes made a big difference.....
Simon Moses yes, this is often the case. Sometimes large changes are necessary but more often a few small adjustments get a bike fit where it needs to be. thanks for watching!
Very interesting! I noticed his hands rarely rest on the hoods? Surpised that wasn't a main focus point.
Execellent video, as I have a lower back spine/disc problem, would like to know the execises you suggested the man should do please.
Excelent video,very interesting, thanks very much!
Edi Petcu thanks for watching!
Awesome vid, certainly gives me something to play with.
Thanks for the very helpful videos. Do you have a video for adjusting the bike fit for standing positions? When I find a fit that is good for seated positions, it is usually not very good for standing positions such as climbing on the hoods or especially sprinting in the drops. Comfortable seated positions lead to handlebars positioned too far back for efficient power transfer during standing.
IMO, a bike fitting is more important than the bike itself. I wish I learned this earlier, before I brought the wrong size bike...
Can this video relate to a mountain bike? If not would you do a video like this one with a Mountain biker please.
Very interested!!! Well done👍🏻
Hi, John! Amazing video again!
It's intriguing seeing the saddle moving aft and the pressure distribution moving even more aft.
I had the impression he had his ankle too high at the bottom of the stroke, like too high a saddle, and he also locked his elbows. Were these an issue?
I don't know if you want to share this too, but did you move the cleats all the way back?
As a general question, he looks like a sprinter. Do you see much difference in the fitting between "sprinters" and "climbers"?
Thanks!
Incredible
The best advise would be to get rid of that huuuuuge pump underneath the top tube.
Good Video.
Thanks for the great video. I have a similar issue on trying to stretch the upper body further. Would increasing the stem length help in achieving the same results?
This is a great video! Where is your shop located?
Great fit video, thx
Awesome video
My bike fit is on Monday with the current 24h World TT champion.
I’m a little nervous tbh I might end up having to buy a new Stem or even worse a new bike. It will be great to know my cleats & position are perfect when I’m on long hard rides though.
How did your bike fit go?? Was it at Peak Sports? Can you recommend that bike fit and what differences did it make to your riding?
@@derekrobbins6735 I ended up been much further forward so generated more power. Talking a couple of watts. Also had small cranks and bars fitted. Aero gains and pedal efficiency. Plus you get insoles fitted to help your feet put power down. Cleats moved back.
Then you get all your measurements typed into a spread sheet for you to keep. Great guy Andy.
@@adammillsindustries. Thanks for taking time to reply!!.....So all in all, it sounded like money well spent
@@derekrobbins6735 You won't regret it, he coaches some top athletes and is class himself. If you book in say Adam Mills from Elmsall road club recommended :)
@@adammillsindustries. Thanks for the feedback Adam, it's always good to hear first hand whether these investments are worth it and pay and if you notice the difference afterwards?? I was watching the Sigma guy doing bike fits as well.. I will definitely have a bike fit at some point in the near future to optimise efficiency and therefore enjoyment..Cheers
I always hav one knee pain after every single ride, does it mean i need cleats wedges? Thank you
Make sure your cleat position is correct, then you will likely need to adjust the saddle; height and fore aft.
Thank you very much, helped out a lot.
Good video. Thanks.
Do you feel, that for a beginner cyclist who is riding an 'entry level' road bike - is a professional fit of benefit? Is is worth it? I ride a bike that is only worth $1K... a proper professional fit is $400... worth it?
Hi! I know very little about bike fitting, aside from being aware of the main variables that can be modified, but I was wondering why in the case of this particular client the pressure pattern on the saddle didn't appear to you as problematic to begin with, and I'm implying by this that to me it appears that the rider is sitting way too forward in relation to the saddle surface. From my understanding the pressure points should be distributed across as large of a surface as possible on the saddle in order to minimize saddle discomfort and localized excessive pressure points over time, and from my understanding the only way to alleviate the pressure to what would appear to be a "healthy" degree in this case would appear to be by moving the saddle forward significantly. I don't really understand why the action of moving the saddle forward would necessarily imply that his hip would move forward (which is what you are trying to avoid), wouldn't he simply sit further back in relation to the saddle surface if you moved the saddle forward? wouldn't it come down simply to the rider's self discipline to ensure that they're able to "drop" their weight in the right area of their saddle? It appears to me that if the saddle is too far back for the rider, it may not be possible for them to drop their weight in their particular saddle's sweet-spot. Any clarifications would be very appreciated, cheers :)
Where are you based, how much do you charge, and generally speaking how thorough are your fit sessions? Also where did you learn to do Bicycle Fits? Thank you
I'm based in Grand Junction, Colorado, and as of the writing of this my bike fits are $300, but subject to change with the season. I'd like to think my bike fittings are very thorough since I usually spend a total of 3+ hours with my clients. I learned to do bike fitting by doing -- I've been a physical therapist for 20+ years and used my background to come to reasoned bike fit solutions with early clients. The more fitting I did , the more I learned. Now two decades later, I'm still learning but I get completely surprised much less often
Bike Fit Adviser can you recommend anyone in the LA area?
Excellent
Hi. I changed my pedals and also changed cleats. I have a problem with my left leg. Cleat adjustments are identical, I changed position of the saddle but I can't find right position maybe the right cleat adjustment. Because after a hard session or soft session I feel pain back of my knee and my calf muscle hurts like someone stabbed a knife to it. This happens only on my left leg and I think maybe my left leg is shorter than right leg. I suffered it band syndrome on my left leg and edema on my left knee 2 years ago. I think something is wrong with bike fit and I can't figure out what am I missing? I wish I live where you live and see you for this. Thank you for the video by the way.
Can you kindly tell us how much you moved the cleats back in this video? And for a rearward cleat position, how much the saddle height needs to be lowered and the saddle needs to be moved back by how much? Thanks
We only moved the cleats back slightly less than 5 mm. In this case it meant a similar change in saddle height although the amount of saddle adjustment might be more depending on how quickly your ankle adapts (and also whether your saddle height was perhaps on the high or the low side to begin with).
really good. but the shoulders angle isn't going anywhere near 90 degrees. so when he get more flexibility you might add stem length?
Good question: One thing to keep in mind is that the 70 degree (or so) angle I was describing at his shoulder runs through his elbow. I referred to this angle because it represented more clearly his reach issues. We can also look at his shoulder angle as it runs from the shoulder through the wrist. Both of these measurements are valid and useful, and there are times when a rider has a certain fit that I might use one over the other.
That said, if memory serves me correctly, his shoulder angle through the wrist was around 84 degrees, so this still illustrates our problem -- I was taking so many measurements of him in the drops versus the hoods and in this posture I often refer first to the measurement through the elbow.
In the future, if he did make some significant strides in his mobility (and I had him come in the other day and he's doing well on this front) we might lengthen his stem, but first I would re-assess where he's sitting at that point on the bike and if his hips were far back enough, then we might consider changes to the stem.
Thanks for watching!
Bike Fit Adviser Thanks for reply. I have similar flexibility issues due to sedentary job (it pro), so was really interested. I'm 177cm 84,5cm inseam and 61,3cm from inseam to elbow and use a saddle height of 74,3cm with keo2 and saddle nose to handlebars of 53cm with a Slr Flow. Height difference from saddle to handlebars is of 5,5cm: a little too low but I have neck pain with more.
Dear Fit Advisor, what brand of saddle pressure mapping device are you using?
Thanks much,
Mark Bedel

MTBer here. Mind quick hint on IT band issue? Done over 700miles on what I thought was a perfectly fitting bike minus weird toe in feeling in my right foot even thought cleats were positioned identically. Rode like that all 2020 and was fine but after couple longer rides this year with brake for winter...pretty significant pain in the right knee. Would toes slightly out relieve the IT band from over stretch or does it have to be perfectly centered for least resistance ? thanks
Seems like bikefit for roadies only
Wouldn't a longer stem help with extending the shoulder angle? And also bending the elbow a little?
But then he would be sitting further forward in the saddle and his hips would be over his feet even more. They accomplished a better fit without having to replace any parts.
How much for a bike fitting and where r u located?
Can you recommend a quality fitter like yourself in the Fort Lauderdale, FL region?
I really need you to move your business to Denver.
Is he on his own or your bike?
@bikefitadviser do you have a video like this for triathlon bike fitting?
Where are you located? If not in Canada, can you recommend someone here? I am in Toronto.
How can I be a certified bike fitter ?
Hey man!!! Where is your clinic?
do you ever do a phone fit?
Is there someone in the UK that provides this service?

I had just done the same thing you're doing to him but now I have a new bike and they were supposed to set it up the same but it's not. They were supposed to take the same measurements from my old bike set up the same on my Carbonite bike but I cannot find extension that I have on my overbite and I do not want to put it on the nearby for the handlebars like you have on yours races it goes up a little but they say they don't make them anymore because my rag I feel like I have too much pressure on my handlebars my shoulders are sore from riding if only road about 50 miles on it so far it's a big change from my room and invite it's a track I just bought a carbon bike Emonda SL 6 I would love to have my bag set up the right way again for somebody like you I went to the bay area and had it done and it cost me $500 and he put a different seat on and I could not sit in the saddle I was everywhere so I took it off where are you located I would love to have my carbon bike set up the right way 😊
LightHouseOf Peace I'm out in Colorado....
Bike Fit Adviser I live in Turlock California
Bike Fit Adviser are you in Junction? I live in Denver but my parents are in Montrose. I admire the rigor of your techniques, compared to the touchy-feely philosophy of most fits. I'm 6'8" and on a 64 cm Specialized with a 130 mm stem and the saddle jammed back. If anyone needs custom, it's me. Sadly, I recently broke my hip in a crit. When I get back to riding, I'd like to go back to square one, and fit is a big part of that.
Is it possible to fit fit bike online?
Where are you located ? Really need to get a bike fit done from you lol
1:34 he seating stabilized because hes wayght increased on sadle per stroke... that makes u want to get out of saddle when u go hard.. i dont like that... i heard that nowadays ppl tend to go forward with hips to feet ratio cuz it alows to put more eficient power to pedals while seated.
Under load most people will gravitate forward on the saddle and this often has to do with the fact that it makes it easier to "get on top of the pedals" because we naturally will tip the torso forward into a more aggressive position - it can feel challenging to generate power when we lean our torso forward AND try to keep our hips back on the saddle.
It's natural to tip the torso forward because by doing this we can get more power out of the large glute muscles that wrap the backside of our hips and butt because we are stretching them slightly. When we';re sitting upright on the bike the gluteals are closer to their position of active insufficiency and so don't generate power as well as they do when we stretch them slightly by leaning forward. Hope this answers your question. Thanks for watching!
Yes but why u moved him backwards then? Isnt it best to make him comfy being bit forwards.. to me working with gravity is mu8ch easyer.. than trieing to push me backwards.. and i dont believe that pushing strokes forwards increases saddle stability.. its just because i sayed hes haveing more wayght on rear and strokes doesnt afect his botom as much as haveing wayght more above cranks.
I somehow took this as wery logical concept where bike fitter talks about importance of aproximet centre of gravity that has to be slightly in front of bb as a general rule of bike fitting for raceing. Cuz to me.. i find it the best when strokes are like standing up work haveing the most of my weyght to play with rather than pushing forwards. And all the rest comfort things and aero stuf must be worked around that centre of gravity being in front of bb.
Mkay but he still has fully straight arms! In such position, the elbow will start to hurt after 10km and next day he will be dying from the pain.
So bikefit is a guessing game
I think his biomechanics is not that good which can be seen with his posture. He is slouching too much. Some bike fitters suggest extending one's body while cycling, like a turtle.
I believe that would be Newton's 3rd law!
Nnnnew sub!
