Knee Pain

Two things happened at MM and I think one may be the cause of this knee pain.

1 - I changed the SPD pedals on my MTB bike. Same brand and model as before and as those on my SS, but for some reason they seem to have a lot less float.

2 - I crashed at Mountain Mayhem many times (it was very muddy) and one of the crashes twisted my knee quite badly.

did you change your shoes? the pedals need to have a bit of float but the shoes are more important. make sure the cleat is attached at the same angle that your foot naturally hangs at if you were to dangle your legs off a table.

but it actually sounds a lot like you could benefit from a shim in the right shoe to angle your foot. a lot of knee pain caused by cleats is down to stretching ligaments as the lower leg rotates through the pedal. the cleat prevents the foot from rotating, causing small unnatural stretching through the knee. you only feel it after a couple of hours riding, by which time the damage is done. i find specialised soles are great and come with a pack of shims - orange to raise the inside of the foot, yellow for the outside for weirdos like my left leg, which rotates inwards on the downstroke. i have mavic shoes and the original soles were rubbish, nearly ruined me.

otherwise, it's probably that you damaged ligaments in the crash. best to see a doctor or physio.
