I built up a fixed gear last month on a bottom-rung 80s Centurion frame. Decent bike, but the geo is pretty lazy, and its relatively heavy compared to what's out there now. I'm not a weight freak, just sayin. My gearing is 42:13, about 85 gear inches.

This Sunday I'm going to take it on a 65 mile ride that I have done once before on a '77 Schwinn Typhoon (cruiser). THAT was a little ridiculous, but I made it. If all goes well, I plan do to this a couple more times then take it on a 120 miler.

Just want to see if I can handle my legs moving constantly for that long.

I'm sure someone here has done long rides on a fixed since I've heard of people training on them to improve cadence. Got any advice?


(Of course, I will be properly geared up with everything I'll need for a ride like this.)
