Your Bike Fit Did Not Help: What to Check Next

Rather than guessing, measure your actual position with your own camera.

First: how long has it been?

The most common reason a fit "did not work" is that it was not given time. A new position feels wrong before it feels right, your body has adapted to the old one, and muscles that were underused suddenly have to work.

Give any change two to three weeks of normal riding before judging it. Discomfort that is fading week by week is adaptation. Discomfort that is identical or worse after three weeks is a real problem.

There is one exception: sharp pain, or pain that appears immediately and gets worse within a single ride, should never be ridden through. Go back to your old position and start over.

Cause 1: too many changes at once

If your saddle went up, the stem got shorter and the cleats moved in the same session, you have no way of knowing which change helped and which one hurt. They can also cancel each other out, a higher saddle plus a longer reach can leave you more stretched than before, even though each change was individually reasonable.

What to do: go back to the position you know, then reintroduce one change at a time with two weeks between them. Tedious, but it is the only way to get an answer.

Cause 2: the change was too small to matter, or too big to tolerate

Saddle height changes of 2 mm are within the noise of how you sit day to day. Changes of 15 mm at once are usually too much for your body to accept, and the discomfort you feel is the size of the jump rather than the destination being wrong.

What to do: move in steps of about 5 mm and ride each step in.

Cause 3: the wrong thing was adjusted

This is where a lot of self-fitting goes wrong, because complaints do not map neatly to causes. Pain at the front of the knee genuinely does point at saddle height. Pain at the side of the knee usually does not, it points at cleats. Numb hands are rarely fixed by a new saddle, and saddle sores are rarely fixed by a new stem.

What to do: work from the symptom to the likely cause rather than from the adjustment you happen to know how to make. Measuring rather than guessing is the point here.

Cause 4: it is not a bike problem

Some complaints look like fit problems and are not. A leg-length difference, an old injury that changed how you move, arthritis, a nerve issue, or a pelvis that does not sit level all produce symptoms that a fit cannot resolve, and sometimes cannot even detect.

Signs it may not be the bike: pain on one side only that survives cleat and saddle changes; pain that also happens off the bike; numbness that lasts hours after riding; weakness rather than just discomfort.

What to do: see a physiotherapist or sports doctor. A fit optimises how you sit on a bike; it does not treat a body that has an underlying problem. Any fitter who tells you otherwise is overselling.

Cause 5: the position is right but the load is wrong

A position that is fine for two hours a week can hurt at eight hours a week. If your riding volume increased around the same time you changed your fit, the fit may be innocent. The same is true of a big change in terrain or gearing, long climbs in heavy gears load the knee far more than flat riding.

What to do: hold the position and reduce volume for two weeks. If the pain settles, it was load, not position.

When to go back to a professional

If you have worked through the above and still have pain, an in-person fitter is worth the money, specifically one who will watch you ride and check cleats, leg length and pelvic alignment, not just measure angles. That is the part a video analysis genuinely cannot do.

Bring your history: what you changed, when, and what happened. A fitter who knows your last three positions can help far more than one starting from scratch.

Measuring where you actually are

Before spending again, it is worth knowing your current numbers objectively. A BikeFit/LAB analysis reports your knee extension, hip angle, torso lean, elbow angle and saddle fore/aft against the target range for your riding goal, so you can see whether your current position is genuinely outside the sensible range, or whether it is fine and the problem lies somewhere else entirely. Knowing that a position is correct is as useful as knowing it is wrong.

Rather than guessing, measure your actual position with your own camera.
