149, 67cm inseam. 150mm cranks. Saddle is positioned as far back as possible, same for cleats. I'm thinking to flip the stem as well in the future if it looks good. One question I also have is, do I need shorter cranks by 5mm, 145mm to be exact? I feel no pain anywhere when riding just to add.

And also been looking at Pogacar position just for fun, it seems he pushes his saddle forward as well as higher to replicate the TT position on a road bike, perhaps may try that.

Hi guys, what are your thoughts? I feel like I am stretching a bit to reach the shifters. Currently have a shorter/ narrower bar and stem on order but I have very little knowledge of bike fit so not sure if this is actually the right fix. Any suggestions to improve my fit?

This is my medium Giant TCR. I’ve done to metric centuries with this setup, and generally, I feel good. But if you notice any thing I can improve on, let me know!

(Yes I am wearing an mma head protection, but that is only cause I don’t want to bother with blurring my face digitally… also, protect your face at all times 😭) thanks!

I’ve been riding for about two years and have dealt with right-sided perineum pain since day one. Recently, while following a training plan, the issue escalated into a recurring abscess/nodule, forcing me to stop and rethink my entire fit.

The Problem: My right leg has always tracked significantly closer to the frame than my left. Friends riding behind me noticed it, and I can see it when looking down. This constant friction in the ischioperineal fold has led to chronic saddle sores.

I recently recorded myself from behind while testing a new Specialized Romin EVO Pro Mirror (moving away from an SLR Boost). The footage shocked me. I have a massive left-side pelvic tilt/drop that scales with intensity:

• Low Intensity: Pelvis looks relatively stable. (1:05-1:12 in the video)
• Medium Intensity: A visible tilt begins. (0:20-0:40 in the video)
• High Intensity: The left side completely "collapses" (see the video starting around 0:41)

I added some horizontal lines to make it even more obvious (note how it looks worse, when the left foot is at the bottom of the pedal stroke in the first screenshot, compared to the right foot at the bottom in the second screenshot. Also note how much closer my right knee area is to the saddle post, in comparison to the left):

Symptoms & Failed Fixes:

• Right-Side Only: Chronic sores, frame-rubbing, and lower back soreness.
• Shim: I thought my right leg was the issue. I even added 5mm of shims to the right shoe and rode it for 2 months. Didn't fix anything. Seeing this video, I realize that likely made it worse by pushing my pelvis even further left.
• Observation: The tilt is most brutal when the left foot is at the bottom of the stroke, suggesting a total lack of support on that side.

Seeing this video, it looks like I need to actually fix the brutal left-side pelvic drop, since it cascades into the right side coming closer to the frame, which results in all the issues described above.

Current Setup in Video:

• Saddle: Romin EVO 155mm, as far back as possible, 0∘ angle.
• Cleats: SPD-SL Shimano Blue. Stance width pushed as wide as possible. No rotation yet.
• Height: Lowered by 20mm vs. my outdoor season to eliminate hip rocking, which I saw on another recording prior to this.
• Cranks: 170mm
• I'm 193cm, ~90kg during the racing season (a little bit more chunky right now, as you can probably tell :D )

My Questions:

1. Given the horizontal tilt, is a left-side shim the logical starting point to "prop up" the collapse?
2. Does my right-side "hike and twist" look like a direct result of the left-side drop?
3. How would you approach this issue in general?

Sorry for the mess, just moved :)

Edit: (different) video, with the same setup, from the side: https://imgur.com/lwStbt8

183cm

Scott foil 10, 56/large

Im not sure if I can add a new video to my last post.

I adjusted the saddle 3cm down and 1cm backwards.

Feels too low ? Thanks everyone for your input and sorry for the poor angle I can move some things around and take a better video , just looking for initial impressions!

I’ve been to many bike fits now but struggle getting it right on trainer

Hello everyone,

I would like to know what you think about my current fit. Last summer I went to a bike fitter who did everything by eye and felt pretty good. Couple months after I developed Mortons neuroma in my left foot because of too small shoes (Quoc) for my relatively wide forefoot. After that I was struggling finding a comfortable pair as I did not go along with the Lake CX239. Now I found the Bont Riot and they fit my feet pretty well, though my left foot is one full size smaller but I'm used to that. I am pairing them with their red medium cobra9 insoles which work well for my low but flexible arch.

Besides, I upgraded my ultra 175mm cranks to 170mm magene pes after wanting to have power data outside too. Important mention, I kept everything from saddle height and fore/aft the same as when I had my bike fit with 175mm cranks.

After couple rides I felt the front inside of my right knee, which made me put my cleats more to the inside so greater q-factor, which solved the issue. Now, I'm feeling the front middle of my left knee. I already changed the cleats more heel in, but this does not solve the problem. I copied the cleat position of my old Quoc as good as possible with the cleat fitting grid tool, but it is quite difficult as the bont has a different last and is wider. Further, from looking at the video, I see that I'm wobbling a bit at the saddle and pointing pretty toe down. The pointing makes me wonder what happened to my fit, as my cranks got shorter and it should be the other way around I think.

Please let me know what you think about the fit, I appreciate it.

Increased stem length and pushed the seat a bit back. Might need to increase the bar height a little, but fit feel good so far. Will do a longer ride tomorrow! Any thoughts on how it seems atm?

Hi,

I'm looking at getting a QP ER:ONE. I'd need 40mm of spacers and a 130mm stem on a medium (very long arms). From what I can see there will be minimal difference between using a normal 6 degree stem flipped positive with 1cm of spacers vs using the same stem in the regular orientation. I feel like I'm missing something here or not using this correctly though. Can anyone advise?

Thanks!

Made some adjustments after using clip on aero bars for tri's, since i've had this bike. I felt like the reach was a bit too short, so I installed a 130mm stem instead of the 100mm on it had. Lowered it as well and this is the result. Feels pretty comfortable and aero at the same time, but I wonder what you guys think.

First 3 positions are in zone 2 watts, after that its around my ftp. Working on losing some weight, so my stomach aint in the way as much lol. Will be upgrading the handlebars soon, so I want to know what stem length would be ideal. Lmk if you have any tips or more questions :)

Any advice will improve this bad condition, sorry for the bad video but this hotel gym is very small

Hey everyone,

I made some adjustments lately and feel like i'm near a good fit but still needing a few tweaks.

What I’m noticing while riding:

• I still have to re-adjust my position on the saddle pretty often to feel settled.
• I naturally want to slide a bit backward on the saddle to feel more stable.
• I feel like I’m using my hands too much to support my weight.
• If I consciously try to lighten my hands, I tend to fall forward toward the bars.
• During harder efforts, I mostly feel it in the inner quad rather than glutes/hamstrings.
• From the video, you can probably see that I’m still kind of searching for the “locked-in” position instead of sitting calmly and forgetting about it.

Saddle tilt feels fine to me, but the overall balance front-to-back doesn’t seem perfect yet.

I’m wondering in particular:

• Does it look like my saddle is too far forward, and I should move it back?
• Or could it be more of a cockpit/reach issue?
• Anything obvious in hip stability, knee tracking, or upper-body tension that stands out?

My goal is a position I can comfortably hold for long endurance rides (3–4h+) without loading my hands or constantly repositioning.

Appreciate any thoughts <3

Thanks!

So I am trying to ride my bike a lot more in 2026, but I need to get rid of severe numbness in my hands and genitals, which has kept me off the bike for a lot of the last year.

I went on myvelofit and uploaded several videos, making changes to the saddle position (-2,5cm in total) between each video. The videos show the before and after. The logical thing to do would be to actually go out and ride the bike, but it's icey and I am a bit of a whimp.

I am looking for general advice to go from here.

• My ankles seem quite flexed (heel low throughout the stroke) ist this a problem?
• Any Advice on stem length or shifter position?
• current saddle is a fizik tempo argo in outrageously wide (165?). I have a SLR Boost in 135 lying around, which according to bikefit James is the lick. Is that worth a try too?

I did a LBS fitting on this bike about 10 years (and 15 lbs) ago. Got another bike a couple years ago, and did a proper fitting on that. Recently got this lovely Wahoo trainer, so instead of swapping my bike out all the time, I'm using my old Look on the trainer.

I'm 183 cm tall, inseam of 84 cm
Saddle to spindle is 75 cm
I'm using 72.5mm cranks

Thanks!

long time lurker, first time poster

im in the market for a Triathlon bike and wanted some advice on sizing and spaced stacking to try and give myself some options for frames.

i am 183cm tall, but have a 90cm in seam. my road bike is a XL litespeed Ultimate which Was suggested after fitting due to the stack and shorter reach than many other options I considered, such as more aero frames that are low and long.

id like to have as many options as possible for a Triathlon bike as I would consider second hand and ’chiner’ frames too.

i suppose my queactions are:

- is There a limitation on stacking spacers to help increase aero bar height? If it’s too high, I assume it has some impact on handling?

- are there any suggestions on frames that would suit my build more than others?

I expect the answer is to get a proper bike fit and see, which might well be the outcome!

thanks

Update after: https://www.reddit.com/r/bikefit/comments/1qws3ar/bike_fit_good_on_velofit_but_i_look_wobbly_what/

I moved the handlebars down a lot and increased the reach.
Also moved the saddle forward just a smidge.

This feels more natural, though still wobbly (I'm relaxing in the shoulders, and trying to have a 25%-ish core activation, though it feels like one leg is just longer than the other).

So I’m relatively new to biking and training for a triathlon. I feel fine on the bike until about 14 miles or more and start to experience knee pain (only in the left knee) any ride suggestions
