Hey! Take a look at this carbon fiber flat pedal. It's completely machined out of carbon fiber, and the only metal parts are in the spindle assembly. Traction is said to be great with a rubber soled shoe. Apparently, a mountainbike version is in the works. No word on weight, but it felt light! Durability is unknown, but be sure; Guitar Ted Labratories will stay on top of this developing component news for you!
