Easton Flatboy DH Pedals
Easton pedals are the choice of top racers including Brian Lopes, as well as top teams like Team Intense. Why? Because they want the performance advantage that comes from Eastons thoughtful design and engineering. O-rings are preloaded to eliminate unwanted "free spinning" when feet are off the pedal.
I have ran a pair of these (on a couple of different bikes now) for about 7 years. I have never once maintained the bearings, and they spin exactly like they did when new. They are gouged and scratched, and even survived a rock that snapped a crank arm. Yet still the spindles are straight and the bearings are tight. They are slightly thicker than the newer pedal designs, and have a mild concave curve for your foot. This is a simple, old school design that hasn't needed redesigning for a reason.
