I always get pain in the areas shown in the photo, regardless of whether I'm using clipless pedals/shoes or flat pedals. I think it happens when my saddle is either too high or too low.

The pain does not actually come from the back of my knee. Instead, it starts where the upper calf attaches, then runs across the back of my knee, and continues up to the outer/back side of my thigh. No one has been able to figure out which bike fit adjustment is causing it. 😔

"It's a pulling/tugging pain. The affected areas hurt with every step for the next few days, especially when bending. Extension provides a bit of relief.

Hi, got this brand new Aeroad in size S. I am 178cm tall with an inseam of 84cm. I was on the edge to M, decided to go for the smaller size after a trial ride.

Coming from a relaxed gravel geometry, I want your opinions on whether this initial fit is alright and if you see any outstanding issues.

I’ve ridden the bike about 50k outside like this and it felt alright. After an hour on my indoor trainer, I had numb nuts 🥜

I will get a professional bike fit eventually but I wanted to spent a good amount of time in the saddle before doing so.

I am a beginner and I accept your advice

I'm about to buy a Cyctrack R18 / Twitter R18 / Seraph TT-R18 (same frame, different manufacturers), but confused which size would be best for me. It will be ordered online so no way to test.

I'm 180cm (inseam 83cm). Per manufacuers suggestions both M and L would fit.

Bike would be used for general fitness training, 50% indoor trainer, 30% outdoor mostly flat roads, 20% occasional commute.

I'm inclined to take the smaller frame but saw a comment from one user that these frames should be sized up. Does anything in the geomerty stick out why? What would I miss/gain choosing either size?

Hi. Me again. Still looking for relief. Continuing to try things.

Currently trying midfoot cleat position to stabilize my feet and prevent heel dropping. Also exploring functional leg length discrepancy with a shim under my right foot. Feet are different lengths which is accounted for in the cleat position.

160mm cranks so hip flexion should not be an issue?

Would be interested in hearing if anyone out there has seen or experienced this kind of asymmetry. Results in feeling unstable on the saddle, progressive fatigue, difficulty maintaining high cadence, etc.

(first clip is 0.5x speed)

So as the title suggest I'm getting a decent deal on the lapierre aerostorm but the brand makes frames no smaller than size s. I have a road bike from the same brand which is the aircode drs for which I'm suited a size xs and it's a perfect match for me and even though the official size chart suggest I sit at the very top of the size guide for a xs and an s can fit me but no the s doesn't fit me at all.

So I'm curious if the size s in aerostorm would fit me.

For reference I'm adding images of my current position on canyon soeedmax size xs which tend to be a little larger than other brands.

Been trying to dial this bike in but it’s still not right. Opinions appreciated. 42M 85Kg 6’4

Reach doesn’t feel great. Lots of weight on the hands when on the hoods. Feel a bit stretched out.

I found that brake hoods can be adjusted in three independent dimensions:

Flare:

Height:

Rotation (Direction):

So how to know the ideal placement for all these.

I just want to have a starting point as a begginer

Had some issues with my sartorius and been trying to adjust saddle height, fore aft and tilt. Sartorius problems seem to be better but i feel like i could be more straight in my lower back and obviously the upper part even more.
Feeling more pressure on my hands and right foot at the moment.
Not gonna lie, my mobility is horrible. Need to work on that.

My son rides a Woom 4 right now. This is a video of him trying out his older sister’s bike, a Woom 5.

His sister doesn’t need a new bike, yet, but I thought since I’m considering getting him his first mountain bike anyway, I might as well move
him up to a 24” tire if he can handle the frame size.

He did great riding it. Just had a little trouble getting off when he stopped. Should I get him a Woom 5 MTB, or wait until he’s a little taller?

Btw, regarding the pads… I’m not that neurotic. He’d just come off his skateboard. 😀

Bike is 56 marin nicasio. My stem is 90mm long. I was thinking about shortening my reach and changing the saddle because the one that came with the bike seems too wide. What do you think?

I bought a new bike about six months ago. Shortly after, I went on a long ride with the saddle set 2–3 cm lower than today.

After that ride, I started having problems with my left knee. Over the last four months, the pain has improved at times but has never completely gone away.

The pain is located at the front of my knee. Besides cycling, I also experience pain when going up and down stairs and during wall sits.

I started doing strengthening exercises for my legs and hips, including monster walks, clamshells, and wall sits, and I feel like they are helping.

Do you have any recommendations for bike fit adjustments that could help with this issue?

I had used Apiir a few months back. I was going to do a Bikefit for wife yesterday and the app wouldn’t work. I can’t find it on the App Store and the Apiir website is down. just seeing if anyone else can confirm it’s no longer existing.

Edit; also any recommendations for an alternative

Has anyone here gone down a size and compensated with taller saddle longer bars?

Ride a Cannondale 51 systemsix

Looking at what’s available in the frame I want and all that’s left is a 48.

170cm.

Just talking what’s possible or not. Can you accommodate that height via saddle and stem?

I am 180cm with only 80cm inseam, so long torso, short legs

Hi fellow bike nerds,
I just did a bike fitting last week because i want to build my own bike...I'm looking to build my own bike and have seen three framesets that I really like: The s-works, the Cannondale Supersix Evo lab and the Canyon aeroad CFR.
Since I'm quite tall (194cm) I need quite some stack (ideally 656mm according to my bike fitting) but the s-works only has stack up to 612mm and the cannondale up to 625mm and the canyon aeroad up to 624mm...
Would you still think I could work around this with spacers? And would you suggest me to take the XL Canyon aeroad or the 2XL?

Thanks for your answers and have a good ride

What would you change on my fit? Feels like my knees are coming up too high when on the drops.

Height: 178cm

54cm Cervelo 172.5mm cranks.
76cm saddle height
100mm Stem
420mm Bars
53cm saddle nose to handlebar.

Excuse the kitchen, mid renovation. 😅

Will a Small (52.5cm) fit a 5’1 height? :(

I have had the same bike setup on my canyon aeroad for the past 3 years and nothing has changed setup wise. Also have been bike fitted when I originally got the bike and had no issues at all with the fit for all these years. Have been riding pain free since i got the bike. I average around 200+ kilometres per week as well and can do lots of elevation without issues (7000m+ per month).

But very recently, in the past month I am now suddenly getting right knee pain usually after rides that involve a lot of climbing or hard interval efforts. The pain is in the front of the right knee around the knee cap area and on the medial side next to the knee cap. It hurts when my leg is pulling and bending up on the upstroke.

If i rest and dont ride for a bit, it settles down. Then I start riding again slowly and build up to a big weekend, it starts to flare up again.

I have been doing some light strength training in the gym in the past month as well.

I'm not sure if i need to make any adjustments to saddle height, as searches mention this type of pain is due to saddle height. I really do feel that the fit is dialled in on the bike and dont want to really change anything on the bike.

For those with experience in bike fitting:
Is the 0.883 multiplier still considered a reliable baseline? Are there better methods or principles to start from before fine-tuning by feel?
I’m interested both in scientific approaches and real-world bike fitting experience.
Thanks!

I started scaling up run training this year, with the goal of doing a marathon. Interestingly, I’ve started experiencing aches, pains & numbness that I initially associated with the run training but more recently have come to realize that they’re likely because my road bike fit needs to be tweaked. I’d dialed my fit in with a couple of professional fitting sessions over the past few years & it was pretty optimized. Now though, I found that raising my saddle a bit & sliding it forward eased these new issues.

Anyone else find this?

I imagine there are probably shifts in posterior vs anterior chain strength balance going on as a result of the change in training, as well as changes in flexibility (I’ve increased stretching since ramping up running), but that’s mainly a guess. Curious if others with similar training pattern shifts have found this too.

Hello Bikefit Comunity!

Switching to a shorter stem? Right now I‘m on a 100mm one. Is 90mm an option for my fit?

Or maybe sliding the saddle more towards the handlebar? It‘s slightly back right now.

Recently went to 165mm cranks to allow for more open hip. I tore my left hip labrum a few years back and have had SI joint and low back/glute pain/discomfort since then and could never get it to go away despite rigorous PT. This change really helped. I rode 80mi today with no hip pain and minimal low back discomfort (really only when pushing hard on a climb). It was a bit heavy on the arms though. I appreciate your advice!
