*Great **Latest.Bike** , good looking, good suspension and love the gearing. I've tested some bikes that were more then twice the price but not as good. Get lots of looks when riding.*

The 3D analysis is outstanding. I can imagine the real benefit not just for elite athletes in injury avoidance, but more so for those people who may be spending longer hours riding in an inbalanced position.

Daniel Montgomery yes, absolutely. Being able to see and quantify small imbalances (and small improvements in them) is critical to making headway with fit issues. And I see much more up-side for "regular" cyclists versus pros and elites. 90+% of the riders I see are "normal" and just want to be more comfortable, feel balanced on their bike, and perhaps gain a little efficiency in the process.

Amazing video. Thanks for all the knowledge!

Love all your videos, very useful and informative. Can you do a video on the topic of road bar flare?

very informative thanks - i rode semi pro for years and virtually had my cleats all the way back on my sidi wire shoes ( size 46) gave far better stability and excellent power delivery on the pedal . I'm not a sprinter so didn't need that instant power which you would bet with the cleat a little further forward. However only recently I have found out I have a 1cm leg length discrepancy , so balanced it up by meeting it half way with a wedge and a superfeet flat insole .

Loving your channel - you give great advice 🚴🏻‍♂️🚴‍♀️

Holy sh!t, that software is awesome. I think I'd like to get checked out. Cool vid, brah.

I'm by no means an elite athlete but have been riding for a long time. When I started with clipless pedals I didn't know where to put the darn cleats. I put them dead in the middle of the mounting holes and left them there. Only in the last year since getting my hands on some really great shoes that I made the effort to make sure they lined up with the balls of my feet. To my surprise I did feel a difference. I've no idea if they are angled properly, but the cleat does have a 5% float so figured that would take care of the angle part.

Gods bless you, John! Not exaggerating at all. Best bike-fit videos. Please, keep on going!

I'm just a hobbyist but learning so much. Thanks!

Interesting. I had my cleats to far forward and saddle a tad too high so I was mostly plantar-flexing. The lack of tension on my achilies meant it took a lot of vibration in it's weakest position and achilies tendinopathy (heel pain) snuck up on me.

The bests videos about bikefit on utube, totally technical content! Keep this good job! Hugs from Brazil.

John, a very helpful analysis -- as usual. Many thanks. John in the Peak District.

Hi, I have already been at bike fitting specialist but still having problems with left leg 'burn' My PM reports R leg as stronger and that was also confirmed at BF. What could be the reasson for pain and occasional burn in my L leg if BF is right?

I’m almost positive if I did this my foot angles would be negative at time, especially at the bottom of the pedal stroke. Does that generally mean my seat is to low?

Did you lower the saddle height to compensate for shorter effective leg length?

After a lot of trys I would set my right cleat 5 mm forward compared to my left shoe. Is this o.k. or would you say this is a no go ?

Is there any method of transferring SPD-SL cleats from my road bike shoes to my SPD cyclocross shoes?

how would you adjust the cleats on a shoe that has no slots for moving them? Mine has the mounting points fixed and I can only adjust the angle of the cleat

I have a misalignment of the leg axis resulting from a 1.5cm leg length difference. No bikefitter can help me. I already have cleat wedges of 7mm under the shorter leg. I cannot exert any pressure with my left longer leg. on every tour I change the saddle height or something else at least once.

My plantar fascia has been hurting since I went from 7 speed road bike to fixed. Cleats are not an option for me rn but I’m trying to understand where should my weight be centered when starting and slowing down ?

It seems to me hard to understand just what you're trying to say.

Are you sure you are measuring the angles that you think you are measuring? At 2:45 - 2:48 it gives a 65.32 degree angle from horizontal but just look at the right foot toe-down: it is at least 80 degrees w.r.t. horizontal! I would have said that maybe there is a lag in the measurement -- but the values never get that high anywhere in the cycle.

This is fascinating. I’m curious if hip imbalance (one rotated forward) might cause her to have to overextend on the right side versus the left hence the angle of the right foot really anywhere on the pedal stroke is going to be greater than the left.

I sit off center, noticeably so to those riding behind me. Lots of saddle pain till I got a Specialized Mimic, but still mechanically crooked and wondering whether changing my cleat position on one side might help.

i just wonder who told her to put the cleat all the way forward in the first place

What about the placebo effect ? Did you tell her "well, your foot angle is not optimal, we're going to work on it" and then subconsciently she may have changed the way she pedals ? Or did you change the parameters (cleat position here) without telling her what was wrong ?

+GoustiFruit φ you're exactly right about this. I did a video a while back about shielding the rider from some of the info as you do a bike fit specifically for this reason. In this case I did not tell her much initially...I mostly said that I thought the changes were going to have a good effective on what we needed to see, but without telling her precisely what those changes were. She did know that they were about her feet and we talked briefly about the foot angle. But we didn't go into depth about how the foot angle would change or the asymmetry until we'd tested a second or third time...

Noticed in the video of her actually pedalling around 1:50 in that her right foot and ankle are really twisting off of the pedal to the outside on the downstroke and pulling back into alignment on the upstroke? Seems like a problem as well...

Do cleats have to be even on both shoes? I have my left cleat a bit further forward than my right cleat. This is what feels best to me and I also notice I naturally place my feet in this manner on platform pedals. Am I doing something wrong or do I have bad habits or could uneven cleats be okay for certain people?

@DJWolves97

Sebasstian86 I don't think so... I probably have the same issue as you do, my feet have different sizes so I usually run my longer foot with the cleat farther forward. I would recommend setting your cleat position to where your feet are almost or completely flat at the bottom of the pedal stroke

@dsego84

I do the same thing. When it feels right there is like a 5mm difference. I suspect one foot is bigger and also there could be a length difference between legs or hip imbalance.

Would crank lengths alter this data. Top and bottom of stroke?

so we can take this as, with purposefully different cleat setup we can train each leg differently. maybe rotating cleat setup every 2 weeks or so so each leg takes different load distribution.

Hey Jon, I'm not sure if you had a video on this but recently all my toes have been aching and itchy sometimes, swollen and little red. This happens after a bike ride. Never happen before until maybe 1 month ago, didn't make any adjustments either. Is it possible to have wrong shoes? Poor soles? Tight? They are shimano but was very cheap for the pair. Trying to figure out what is the issue..Thanks if you have any suggestions.

Stevo Reno hi thanks for the reply but I have also ridden these shoes for several years without issue. I used similar brands and fit before for 6 years no issue. My toes can move easily too. The shoes I use are pretty comfy too and breathable. Maybe something wrong with my foot...

@CanIHasThisName

After a certain time in the saddle, my feet start swelling a little bit. At this point, it is important to loosen up the shoe (even if it doesn't feel uncomfortable) so it doesn't reduce blood circulation, otherwise my toes may start aching and feel numb. Socks are an aspect in this To me, it is important to have shoes that are easy to tighten/loosen as needed. Can't say whether or not this is your problem, but may actually be worth looking into.

All of these videos about cleat placement have me very confused. I find myself mounting cleats very close to as far forward as they can go on most shoes I’ve fitted. This puts the pedal axle and pressure across my toe knuckle flex point where I feel the most leverage and power. I don’t experience foot pain. Is this wrong?

Depends on the rider and your style of riding. Your forward cleat position is more suited to sprinting while back positions are more suited to endurance.

This prompts several thoughts: (1) Why not track power output at the same time as you are measuring the angles? I realize that power varies according to effort and cadence, but angles probably change too? (2) Her bike looks kind of like a road bike, so why is she using SPD MTB cleats? Not that one can't use SPD's on the road, but I'd expect an elite road racer to be using SPD-SL's or equivalent for a more precise foot placement?

Paul Flory I run both types of pedals/cleats. I definitely have more flex/movement in my foot/ankle and pedal stroke with standard spd pedals and the smaller pedal platform! Both shoes are bont so both super stiff, but I can’t do any serious road riding on the spd’s as it trashes my ankles.

Hey +Paul Flory , good questions. I'd love to track power through the pedal stroke at this level of accuracy but it would have to be sync'd with this system in order for it to be truly useful. For example on the exact pedal stroke I happen to be looking at, the power would also need to be sync'd into the system and at the moment that's not available. Additionally, most of the dual-sided pedal-based power measuring systems actually estimate the crank angle rather than having it be a "nard-wired"metric. She's actually an elite mountain biker but like most of them spends a ?lt of training time on the road bike...

@paulflory3532

@BFA I expressed it poorly. What I meant was to track power output during the session to see how the changes you make affect power output. Wouldn't have to be as detailed as a force curve through the different positions of the pedal stroke, just power output time-synced to the session. As I said this wouldn't be rigorous but it would go beyond fitting by the geometry. I think my fitter was doing this somehow. I can see how she might want to have ONE set of shoes for both types of training to avoid issues from slight differences in cleat position for the different shoes. At 18 she's an elite? She's racing against the senior pros? Impressive!

@bikefitadviser7012

Paul Flory Oh, okay, got it. So, using power over the course of session *can* be useful but it's a pretty slippery slope. I did a video about this a while back -- namely that power isn't always a useful measure during the course of a bike fit -- for a few reasons. It's difficult to get the rider to pedal at exactly the same perceived level of effort on the before and after tests to see if power has improved....and 5 or 10 watts may be significant and can easily be skewed because the rider may be warmed up more or less on the re-tests, could be just getting familiar with the feel of this particular resistance unit on the stationary trainer, or any number of other things. Not to mention if they know that we're looking at power, it can be even very difficult on a subconscious level to keep that out of the equation -- most riders *want* their fitting to feel or be better and this type of placebo driven effect is really difficult to control for. Which goes back to the idea of shielding the rider from some of the information coming out of the fitting -- I find this to be extremely important and it can be difficult to do this in a responsible and strategic way. Another option would be to test the rider's physiologic response at a given wattage --say 250 watts. This will probably have to go beyond merely tracking heart rate, which would be easy, but is also subject to some of the same issues mentioned before (warmup, motivation etc), but would then mean some more involved (time and equipment-wise) testing. Definitely not saying it's not useful....just that it's difficult to do in a way that controls for enough of the variables.

Agreed. But the point of a fitting is to help the rider develop more power on the bike, no? Simply establishing a geometry that's within "normal" ranges and symmetric may not accomplish that, at least for some people. For various reasons (injury, inherent asymmetry, etc) they may produce more power in a seemingly less than optimal fit A physiologic response could be tested in a way that would not be affected by the rider's psychology, etc.: a lactate step test before and after the fit. Basically what you suggest, holding constant watts at several levels, each for say 7', and then measuring blood lactate. Plotting the results would give watts at the 4mM lactate threshold, which might improve (or decline) depending on fit. Fatigue might affect the results if more than one step test were done in one fitting session FTP is subject to psychology, and HR (a poor substitute when one cannot measure watts) responds slowly and as you say is subject to many other factors. A followup step test a few days later once the rider has "settled into" the fit would be a good idea, because the rider might initially be a bit tentative with the different feel of a new fit?

i have a personal question which is irrelevant to this video. my question is as an not really fit adult trying to learn cycling for the first time what type of tires should i choose? wide ones that are supposed to be more comfortable but less speed, or thin ones that are faster, or something else?(i live in a sort of small town area where i don't have a lot of options about frame sizes and stuff in the shops, they would just adjust saddle heights and stuff to fit someone to bikes, so i would like a short and precise answer instead of too many technical details.)

Ohh really? why do you think I am confused?

11 MINUTES of watching graphs and data. NOTHING ON CAUSE AND EFFECT. This is what I DID NOT learn: if you observe X correct by placing the cleats into Y.

Your info could be solid, but I think (also from watching different video's from you) that the way you present it, the way you tell things, is sometimes incoherent. I think that if you would put a little bit more written preparation in what you want to say, the story you'd want to present would be more coherent. The message you're trying to convey would flow better and be more of a unity. It wouldn't seem too improvised. There's lots of ; haa, eum, so eum haa.... and small repetion phrases indicating that you're thinking about what you want to say. So you end up saying the say thing twice or more, or you end up rephrasing the whole sentence. Not dissing on the content because the content is good and very elaborate. Anyways thank you for putting in the time and effort to explain some of the bio-mechanics.
