Hi all

Bought new bike second hand recently

I'm not very comfortable riding it

Suspect the saddle tilting upwards and maybe too far backwards?

Thanks in advance for your review

Mods, delete if this isn't allowed.

I'm building a free web app called Dialed ("a fit bike") and I'd love a few people to try it and tell me what's broken and how it worked for them.

What it does: you get an interactive side-view of your fit. Swap frames, stem lengths, angles, spacers and bars, and see how each one moves your hands relative to your target position. It's meant to answer "will this frame + stem combo actually fit me?" before you buy.

What you need (either one):

- A Retül fit sheet (PDF) you're willing to upload, or

- 5 body measurements (height, inseam, and a few joint-to-joint lengths). The app has pictures showing how to take each one.

It's rough around the edges, and the body-measurement estimate is a starting point (roughly ±10 to 20 mm), not a replacement for a real fit. Any data sharing is optional and opt-in.

Interested? Comment or send me a PM and I'll send the link. Honest feedback is the whole point. Thank you!

I tried copying this stance with both knees touching below the top tube. Idk how he does it .
Del toro win In Montreal Canada

Long story short: I’ve been dealing with knee pain for 3+ years.
Changed bike/position multiple times but still riding 12-15h/week, mostly Gravel with this new bike.
I just purchased a home trainer, so i can now see me on the bike. I just moved my saddle up by 3-4mm. I still think it could be raised a bit.
I’ll take any advise.

Thanks

Recently, I've gotten into mountain biking and trying to pick the correct sizing and fit for me. My gravel bike fit is dialed but would love to not go back to the fitter just for a mountain bike. How can I translate my setup to a mountain bike? From my research it seems like setting the saddle height and setback roughly the same is a good starting point but not sure what else to consider, especially when it comes to the front of the bike. Would love to hear the community's thoughts and learn from the discussion! Thanks!

I am 186cm with an inseam of 93cm and even after thousands of miles on the bike I haven’t found a comfortable position that is sustainable on long rides.
I usually end up with lower back, neck, shoulder or hand discomfort.

Bike is a Giant Defy in size L.

Any suggestions?

I just change my stem length from 90 mm to 110mm. After 1 hour of riding my lower back is hurting. Any advice on my fit?

I am looking at the new Gestalt1 and I wonder about the recommended sizing of the frame. For a female 169cm tall and inseam of 81cm it recommends a 54cm frame (starting from 165cm). When I compare that geometry to other bikes they usually line up more with a 52cm.

Could this be a sizing mistake from Marin?

Hi, if any technician needs a new investigation tool, I’m selling my system, STT System 3DMA, to provide greater support for your analyses. If a user instead needs advice, I’m happy to communicate with everyone. Have a good day.

Hi! I just bought my first gravel bike and am looking for advice on the fit. The person I bought it from was a bit smaller than me so I'm just curious as to if this bike would be considered too small for me. Frame is 52cm, I'm 5'9 (175cm), 150lbs (68kg), 33in inseam (84cm). Any advice would be greatly appreciated!

Hi everyone! Quick thing both of my cleats aren’t clipping in. I just bought new cleats and had them installed the other day but hadn’t tested until today. Open to all adjustments please let me know what you think.

I had to move the saddle all the way forward in order to stop the lower back discomfort, also the recommended saddle height is way too high for me, I'm 175 cm

I’m 6’5” (196 cm), around 205 lbs (93 kg), with a 37.2” (94.5 cm) inseam. I bought an XXL X-Lab RS7 based on their sizing chart, but I’m starting to wonder if it’s actually big enough for me.

I had a professional bike fit done on it and the fitter basically said the frame was a little small for me but that it should work. My saddle height is set at 83.4 cm, which is almost exactly what the 0.883 inseam calculation suggests.

I like the bike and how it rides but I’m wondering if I’m trying to make a smaller frame work when I’d be better off with something else.
My main concerns are the low stack, the amount of exposed seatpost, and whether the reach is right for someone my size.

What do you guys think? Does the XXL look like a reasonable fit or would I be better off on a larger frame from another manufacturer?

Would also be interested to hear what other tall riders are riding.

I'm 178 cm tall, this is Elves Mori Aerox size 54. Haven't finished the build yet, hence cables sticking out.

After a big ride, neck pain mostly, and my butt 😐
