Are your feet clipped in on your mtn bike?

I've found that a small change in the angle of my cleat in relation to my pedal can cause a bit of knee pain over time (that is, if my toes point in or out a bit too much on my pedals, that seems to put some strain on my knees - nothing I notice right away, but over time it builds up)

So perhaps the knee pain you're experiencing on your road bike has something to do w. how you're clipped in. If so, then if you're clipped in on your mtn bike, you might have a slighlty different angle of you foot in relation to the pedal, since you might be using a different shoe, or a different shoe/cleat system alltogether. And if you're not clipped in at all, your foot is free to move about so you're not putting the kind of strain on your knee you would experience if your foot were clamped in one place.


Just a guess. That'll be 5 cents, please
