One of the guys that frequently rides with us tried to convince me to increase my cadence. It's tough. I find my natural rythm is slower - think Jan Ulrich (slow) vs. Lance (omg fast). As long as my knees aren't out & floppy, I'm doing okay

I am working on increasing cadence, but haven't been able to get to where I can do that and not get tense like I should be sprinting... mentally it feels that I'm putting more calories into moving my legs than moving the bike, and that feels like wasted energy
