The Bike Fitting Mega-Thread

Your arms and upper body definitely look better to my untrained eye, less rigid and strained :+1:

If your hips aren’t rocking lowering the saddle looks good too again my untrained eye says behind the knees/ calves you look less strained there too :+1::+1:

The feeling of extra weight on the hands should dissipate I think when your core gets used to the new position.

Completely off the fitting topic I like having a more flexible arm and body position for control and making myself more visible in traffic and it looks like you’ve got that :+1::+1::+1:

That looks like a great read, I didn’t consider the outdoor/indoor variance either,it may just be getting used to the rotation!

Certainly feels so much better and much less stretched!

Definitely looking better…note the bend in your arm at the elbow, which was not there before. That is a good thing!

How long is your stem? I’d be tempted to put a longer one on, depending on what you have now.

You know I was thinking the same - it’s only. 100mm on there currently-

I’m tempted to try to help nail the position before a new bike purchase next year

Hey guys, I’m trying to refine my position through the winter months and I’d love some opinions! I’m 183 cm tall and ride a size 58 CAAD10 with a 90mm stem. I’ve been riding for about a year and a half and my ftp is 262 watts. I don’t race, but I definitely want to be fast to hunt down those KOMs. I’ve watched basically all the bike fitting videos made by Francis Cade and Cam Nicholls and tried to adjust my position accodringly. From what I can feel, the bike still feels a tiiiiny bit too long (only on longer rides), even with the shorter stem. Do you think I should be on a smaller frame? I also have pretty inflexible hips and seem to rock on the saddle quite a bit, maybe some shorter cranks would help? The ones I currently have on the bike are 175 mm. Here’s a little clip of me cooling down after a training session: VID_20201129_190630.mp4 - Google Drive
Thanks!

Hey y’all this isn’t as much a bike fit question it’s more my pedal stroke.
Recently I don’t feel straight on my bike. I twitch my left leg a lot. What’s the issue y’all think? I have videos from the back and from the left leg side. I’m not in any pain just uncomfortable and have to move around I don’t really get it.

Any help would be great. I’ve been dealing with this for much longer than I should have been. I can finish workouts I can ride just twitch my leg. :confused:

Thank y’all.

You have the files locked out with a need to request access. Do you want to open those up for easier access?

Fixed. Sorry.

  • Uncomfortable how and where?
  • What does ā€œmove aroundā€ mean?
  • How does it address the discomfort?

From the rear, there appears to be a bit of a ā€œwood chopā€ that means the knee is outward from the midline when at the top of the pedal stroke, and comes inward towards the bottom. Not a huge problem on it’s own, but we need to understand your discomfort to know if it is related.

There also seems to be a fair amount of movement at your saddle, mostly left right, but some apparent ā€œbounceā€ if I am seeing it right.

From the side angle, it is hard to say, but you may have your saddle a bit too high. There is a fair bit of toe point. That may be ok, but it seems quite low to me and maybe you are reaching to hit the full stroke at the bottom?

If I try to keep my knee straight like youre noticing it’s difficult like my body says that somethings not right and moves it out.

The bounce is what I mean by move around. Like I bounce/ move a bit to get ā€œcomfortableā€ I guess like reposition myself.
It’s like my body wants to be in one position but I’m naturally shifting to a different one. Idk how to explain it.

I did do some quad stretches before riding Saturday and Sunday, that helped a bit. I’ll put some focus on that and see if I notice any benefits.

  • Generally speaking, you should not be forcing your body into any position or alignment. If you are doing so to avoid pain/discomfort, something is off fit wise. What happens if you just relax and let your body flow as it wants to flow?

Essentially, I’m trying to understand the current state, when you just ride, and what is ā€œwrongā€ with that specifically.

Okay thank you. I’ll report back in a day or two.

Here’s a fun one, I’ve developed a bad habit of twisting my hips to the right a bit and pedaling with my right knee jumps out; a friend pointed this out and made a video, it’s quite bad. On the rollers, I do not so this at all, knee is straight. I started riding rollers more recently, 45-90 minutes at a time.

Thoughts on how to fix this?

Is your saddle straight? If you have an aero seatpost, it obviously must be, but if you have a round seatpost, even a degree to two can make a difference in how your hips sit relative to the frame.

I wonder if people can chime in here. I’m having ongoing right lower back/left hamstring issues, and spent 20 minutes playing around with bike setup. I’ve now got all the spacers and the saddle all the way back, and I still feel like I can’t get my weight far enough back to hip hinge properly. I’m wondering if the bike is actually a bit small?


Edit: apologies for poor lighting/contrast; I can get better footage if someone thinks they could make use of it.

Some quick q’s…

  • how tall are you?
  • what size frame is that
  • how long is your stem

If you have a video instead of pics, that would help too…

177cm (but short legs - 80cm inseam)
That’s a 52, albeit a big one - reach 383, stack 552
Stem 110mm

I have a vid…let me see if it lets me upload it.

Thank you

My initial reaction is that yes, the frame is too small for you…it looks like you are trying to jam you hips back on the saddle to get more reach (and leg extension).

I’m 175cm and I generally ride a 54 (although on my Canyon, I ride a small). 177cm on a 52 seems pretty tight, even with a short inseam.

Thank you

Yeah, I’d say definitely too small…legs aren’t fully extending and you are trying to stretch out / push back to get more room, but there isn’t any.

But that is just my opinion / analysis…let’s see if others have a different take.
