A while back I asked for feedback on FitInspector, the app that checks your bike fit from a phone video. Here's what's new:

• Knee angle is measured on every pedal stroke. Filming twice now gives almost the same number (within 2°, instead of 4–14°).
• It no longer mixes up your near and far leg.
• Shoulder and elbow are measured across the whole video, not one frame.
• Bad frames are thrown out. If it can't see you clearly, it asks you to re-film instead of making up a number.
• Switching from hoods to drops mid-video is handled.
• Recommendations are clearer, so it's easier to know what to actually change.

I'd be glad to hear your criticism.

Hey everyone! I wanted to get your thoughts on my bike fit. I don’t really feel any discomfort, except on long descents where my neck gets a bit stiff, but that’s about it. Do you think the frame size looks right for me? I’m 1m70 (5'7") with an 82cm (32.3") inseam, and the bike is a size Small with a 372mm reach and 556mm stack. Any feedback or advice would be awesome. Cheers!

Hi everyone, I'm looking for feedback on my riding position on a Canyon Grizl 7.

I ran the video through Pedalyze, which suggested:

• My saddle may be too low.
• My knee is ahead of the pedal spindle, and the saddle might need to move back.
• My reach or handlebar position might need adjustment.
• My torso angle looks reasonable in the more upright position.

I'm not sure how much to trust these recommendations without a second opinion, so I'd appreciate feedback from people with bike-fitting experience.

A few questions:

1. Does my saddle height look noticeably low, or would you leave it alone for now?
2. Would you change the saddle setback based on the knee-over-pedal-spindle measurement alone?
3. Does my reach and upper-body position look appropriate for comfortable endurance riding?
4. For the aero-bar position, does the reach and elbow bend look sustainable for longer rides?

Hello. I posted this on bike commuting and someone commented on the fit of my bike. I bought this bike from fb marketplace just to try out a road bike. I didn’t know much about bike fitting other than choosing a frame size based on height. I am 5 foot 2 and this is an XS Women’s Liv Avail 3. I typically use the interrupter breaks and am up on the bars when I go up hills (pictured). I go on the drops sometimes but it’s not my first instinct. Based on these pictures are there any red flags about my bike size?

Thank you

I'm currently looking for a gravel bike. After a pretty quick pre-fit, I was told my target stack/reach would be 610/385. Since that fitting felt a bit rushed, I went to a second fitter. She didn't have a fit rig, though – she just took my body measurements and then recommended one of three frames I'd shortlisted. So after two "fits," I'm still not really sure where I stand. Maybe you guys can help!

My measurements:

• Height: 183 cm
• Floor to sternal notch: 150.5 cm
• Inseam: 89.4 cm
• Arm length: 66 cm (holding a pen), 54 cm (to the wrist)
• Lower leg: 44.5 cm

The bikes I gave the second fitter were the Look G85 Cezal (L), the Avona Calis (L) and the 3T Extrema (XL). Her take is that the Look should fit best, since I'd be in a more aggressive position on the 3T. She based that on the seat tube angles – but the Look actually has a slightly longer reach. Overall, the differences between those two frames (3T and Look) seem pretty marginal – but is there still one that's a better fit for me purely in terms of geometry?

Hey guys, I’m looking at buying a used 2020 Specialized Venge Pro in size 54. I’m 175 cm tall and relatively new to cycling.
My eventual goal is a full Ironman. I know the Venge isn’t a TT bike, but I love the bike and plan on using it for most of my training and potentially racing it.
I’m currently riding my dad’s bike, which isn’t fitted to me and gives me some wrist discomfort, so I want to make sure I get the sizing right this time.
Would a 54 Venge be a good starting point for my height? What other measurements would you need from me to get a better idea?
Thanks!

I'm an amateur triathlete exploring an idea, and I’d like to hear from people who travel for cycling holidays, training camps or races.

When you rent a road, gravel or mountain bike, how do you get it set up to feel comfortable and familiar? Do you send measurements beforehand, bring a bike-fit report, adjust things at pickup, or just ride whatever the shop provides?

The idea I’m exploring is a free “bike fit passport.” You’d create it using guided photos of your current bike, a few details about its components, and the manufacturer’s geometry information to help work out your existing setup. If you already have a professional bike-fit report, that could also provide the starting measurements.

You could then share the passport when booking a rental. It would translate your usual riding position into setup instructions for the specific bike you’re renting—even a different brand, model or frame size—so the shop knows what to adjust before you arrive and where the rental bike’s limits might prevent a close match.

A few things I’d love to understand:

• Thinking about your last rental: how did you handle the setup, and how did it feel on longer rides?
• Has uncertainty about fit ever made you bring your own bike instead—or skip renting altogether?
• What do you already use to record and share your setup, if anything?
• Would you use something like this for a future trip? What would you need to trust it?

Please mention what kind of riding you do and roughly how often you rent. Experiences where everything worked perfectly are useful too!

Hey, I'm fairly new to cycling and now that I've built enough of a base to comfortably survive century distances in either km/mi. I'm starting to do the longer rides with more pace or challenging routes.

Someone pointed out that I have that Ben Healy tilted head style that only comes around during an hard effort and deep into the ride. It doesn't cause any pain/discomfort but I just can't help it.

I've done some light research but, does anyone on here have the same quirk and dove deeper or told a proper bike fitter about it?

This is my second post in this channel but hopefully this angle gives a better view. First road bike, 6ft tall on a Trek Domane AL 5, size 58. Some lower back pain on rides. Looking for any advice!
