Two millimetres: what cleat position does to your knee

Daniel came in with twelve years of a sore left knee. He’d changed saddles, bikes and physios. On the trainer, his left knee drifted in by eleven millimetres at the top of every stroke. His right one didn’t.

Where the knee goes, the foot decided

Your knee follows your foot. If the cleat points your foot a few degrees off its natural angle, the knee has to twist to keep up, two and a half thousand times an hour. Two millimetres sideways and three degrees of rotation was enough to bring Daniel’s knee back over his pedal.

Why we measure, not guess

A cleat looks right from above and wrong in motion. That’s why we set them with you riding, on camera, and check the knee track again after every change. If something still hurts after a fit, we send you to a physio, not to a new saddle.
