Left thigh closer to to tube than right whilst pedalling?

What could cause my left thigh to be closer to the top tube than the right?

My left thigh occasionally brushes the top tube whilst pedalling which isn’t an issue but my right would take a considerable effort to touch the top tube. And when I look down at my thighs, the left is visibly closer.

My left hip isn’t quite as flexible as my right but I have no other leg imbalance/length difference that I know of.

Thoughts?

    Tilted pelvis?

    My right knee brushed the top tube for years, normally under heavier load, climbing etc.
    I improved it somewhat by aligning my knees better with new shoes (S works) which have a built in varus tilt, and also good quality insoles to support my arches.
    If you don't get sore feet at all I wouldn't worry too much about it - might just be your physiology.
    Arch support might help though

    Don’t think so. Good posture and can rotate the pelvis forwards and back without problems.

    Meant to say - might also be worth checking your cleat rotation. If you're toe'd in, this can also cause your knee to brush top tube. Toe out has the opposite effect.

    Arch support for both feet or just the one that’s rubbing the top tube/has further to reach the pedal?

    Presumably your saddle is straight?

    Ok, it may have been wonky, and would explain the saddle rub on one side today but in no way does that reflect on my competency as a cyclist and it could happen to anyone.

    When my saddle is straight, my left thigh is still closer to the top tube.

    Do you dress to the right by any chance.

    Are you slightly bow-legged?

    Nope, legs straight as an arrow.

    I have Arch support in both. I also used to get wear marks on only the left buttock of my bibs, and right sided low back pain. A local bike fitter put shims under my left cleat, and also wedged the cleats, 3mm on left and 1mm on right. Cleats are staggered too, with the left being a few mm further forward than the right, although both are quite far back on the shoe. My right knee still occasionally comes close to the top tube but its usually once I'm very fatigued.

    Without going to an experienced fitter it will be a bit of trial and error, but it certainly sounds like your knee is tracking inside the pedal. Best to only make small adjustments at a time, as its easy to end up with knee pain if the change is too drastic.

  • People are generally not completely symmetrical, if you look at cyclists from behind, like on a televised race, many of them have different positions for left and right legs.
    Does it cause any discomfort?

    If it doesn't cause any discomfort, isn't making you ride into hedges or fall off and this is the first time in however many years of riding you've done that you've bothered being worried about it then I wouldn't really worry about it.

    ive worn through the undercoat on my right frame tube where my leg rubs. I'm not even sure when i do it.
    its probably worth sticking a protective strip on to save your paintwork.

    Doesn’t cause any discomfort, feel stable on the seat, hips aren’t rocking. Weird I never noticed it on any other bikes. Maybe new bike is wonky. 🤷‍♂️

    Best buy another just to check. One of those Pearson aero bikes. They look sweeet.

    Tbh though, i wouldn't worry about it if thats the case.

    I'm the same on the right side due to generally being broken all over but doesn't really make any difference to my smooth, gentle, supreme power making souplesse sur la plaque

    I have also always had this on all bikes, my left knee almost brushes the top tube. Mentioned it to my Dad once and he said he did it too so I just accepted it.

    Maybe this is a sign of being a potential track cyclist talent, with those marginal aero gains. ;)

    She's utterly wonderful. Reinforces the point that Europeans do everything sooooooooooo much better than the Brits.
