You guys that say HTFU are dum.

(just kidding)
Powering 240lbs up a long hill is virtually impossible. We only have about 8-12" of sprint power or HTFU Power. The way to get big guys up hills it so spin, spin, spin.
The #1 mistake that new riders make is riding a gear that is too large and carrying a cadence that is too low.
Some of you guys still don't get it. When roadies would use a fixed gear in the winter for training, they installed a low gear and worked on cadence and pedal stroke. Not churning some huge gear around town.
If you want to look bad-ass...try cruising down the road a 120-140 RPM with a pedal stroke that is smooth as butter. You will be the envy of both FG riders and roadies. Seriously. I've had guys tell me, "Man, I
wish I could spin over 120 RPM. It's just not in me to do it."
