Belt drive fixed

When I did a ramp test for some sport science students I peaked at 300watts. That translates to about 220lb/ft. (From what i've worked out that is.) The 300watts was over a period of time. Just think what the power output would be over a 10/20second sprint.

The Yamaha xt660 only produces 42lf/ft. Slight difference there

Well a very good climber can hit 800 watts, allegedly Boonen has hit 1200 watts hence the need for his custom bikes.
Cancellera broke his chain (physically snapped) while riding in the Dwars (was it?) that would take a fuck load of force alone, bike chains take for more force than a motorbike.
