The Bike Fitting Mega-Thread

Thanks for the feedback. I’ve got some of those. May try and see if that helps.

Did you mess with the met pads on yours?

These are the ones I have: G8 Performance Pro Series 2620 Shoe Insoles | Sigma Sports

So the only thing I did was to put in the highest support plastic “cup” or what you call it. The ones that are interchangeable.

Felt super weird at first since it was like riding with a golf ball under your foot, but an hour in and I was more comfy than ever :slight_smile:

Got the same ones. I don’t have a high arch, so going all the way up would probably be too much.
I’ve heard that the majority of people need the #3 support.

Me neither, because I pronate :wink: So its kind of contradictory. I don’t have the arch, but I should, so I use the highest one to help out with that.

But its worth trying at least to go up a size :slight_smile:

I just finished building a gravel bike early this week. Love the SRAM explore line and how smooth the bike feels, however I’m just not sure the frame is going to fit me. It feels as though the reach is too short and that my center of gravity is way too far forward. However is I address this and move the seat farther back I have to lower the seat to the extent that I I feel like I’m too far down into the frame and my position becomes even more upright. I have a 100mm stem and the same saddle that I have on my road bike. I don’t mind at all to get a bike fit done, but if the frame doesn’t fit me there is nothing a bike fit could really do. I’m 6’1 and have a longer torso than I have legs and also have ridden 58mm road bikes. This is my first gravel bike, but it just doesn’t feel right all all. Almost like I’m simultaneously too far forward over the front tire and sitting up too straight. I have attached some screenshots from a video I had my wife take to this for context. I am on a 3-4% grade in the photos. One other note is that I prefer the saddle to be on the lower side of the acceptable spectrum. Any input would be appreciated. I got a killer deal on the frame and could probably make a few dollars on the frame if I decide that’s the issue and sell it. Thanks!



I think it looks fine?

You look relaxed in the arms, not overreaching.

Maybe saddle a biiiiiiiit too low? But hard to tell since you’re at extension on the other leg than the one facing the camera.

Nice bike!

Went with L4 and R4, maybe could go to the 5. Raised the saddle a smidge and that seemed to help as well.
Still getting a bit of pain on the right.

How are your cleats positioned?

As far back as they will go on my Sidis, same position on my SWorks, compared to the ball of the foot.

Good morning guys,

I’m having a very hard time with my bike fit. I have tried a couple of fitters here in my country, but I have only spent money and ended up feeling worse, so I’ll highly appreciate your input. Basically. I’m suffering from a very hard pain in my left leg. I believe this is the psoas or something like that since it feel inside the leg, then it goes to my lower back, my glutes, my knee but it starts at the very centre of my hip.
My left hand also goes numb all the time. My right side on the other hand (no pun intended) feel great.

I’m including two videos on the trainer (Side and rear) and one video from the outside world. I have also made some measures in case they are helpful.

|Saddle HEIGHT| 68,5cm

|Saddle SETBACK 8cm
|Saddle ANGLE -1° (I measure this one with my iphone)
|Saddle > Handle Bar REACH| 50cm|
|Saddle > Brake Hood REACH| 62cm|

Videos: https://files.fm/u/4afv2hca7

I also attach two screenshots of one of the videos.


If you guys don’t mind taking a look and giving me your thoughts, I’m pretty sure it will be helpful for me. Thanks in advance, I don’t wanna give up cycling but I’m sick of this pain.

Thank you so much

A very uneducated guess but a leg length discrepancy ?

Due to where you favor holding onto the bars (side video) it looks like the bars are slightly too low, slightly too much reach or both. Possibly the saddle could come down ever so slightly as well.

NBD a week ago and my first TT/Tri bike. Got together with my fitter and this is what we came up with. Any thoughts or opinions? Use case is gonna be for ultra distance road events and 24hr TT’s

Bottom is what we started with, top is where we finished

Always hard to judge from a single pic and lack knowing goals, background and such, but with those qualifiers out of the way… it looks fine to my eyes. No immediate red flags that I can see.

Totally get that, once the weather turns and I finally break down and put this bike on the trainer I’ll get some videos. Goal is a position that is comfortable and that can be held for hours on end. Planning on revisiting the fit after giving myself 6 weeks to adjust to the position since I’m new to being on a TT bike

  • That gets the “Chad” seal of approval. I will fit people however they want to be, but the most aero and “fast” position in the world is worthless unless you use it most of the time :stuck_out_tongue:

  • Comfort is the one “real deal” aspect I can control and get actual feedback. Aero and Power aspects of fitting are very real too, but tracking any changes in them are at varying levels of difficulty to sense and/or show. As such, I do consider those two, but usually in a secondary aspect to comfort unless the rider pushes one aspect or the other.

I’m not an expert but that looks like a lot of setback to me. It also looks like you’re quite stiff through the pelvis. Can you roll the pelvis forward a little more, or does saddle discomfort come into play?

I’m theorising that a combination of the wrong saddle and too much setback is the issue here.

  • Based on what, exactly?

Based on 8cm for a sub 70cm saddle height for 1 thing.

The position also looks slightly rotated rearward and the rider looks to be struggling with reach.
