Girlies -

As I've been riding, I notice that a few miles in (which, for the newbie that I am, equals about half way) one of my knees gets tight -- kind of like a rubber band that's been pulled too tight. It's only on the outer side of my knee cap, and if I pull my leg off the pedal and flex it a few times, it seems to get better -- kind of like I'm unkinking it. (Sorry to be so inelegant in my explanation, but it's the only way I can describe it.) It doesn't happen every ride, but when it does, that feeling of "tightness" continues for a bit.

Since it's only one knee, I don't think it's a problem with my saddle height, but I don't know. Any thoughts? Maybe I'm just a weirdo. :-)

Gracias!!
