Wolf Tooth Waveform Aluminum Pedals are designed for all-mountain riding, from XC to downhill. The pedals come in two sizes, and are proportionally scaled to provide a supportive platform, shaped to match the footprint of your shoe. They have a slim, dual-concave profile that is 14mm thick at the perimeter and just 12.5mm thick in the center, cradling your foot for optimal pedal feel. Each side of the pedal has 11 stainless steel rear-loading pins for loads of traction. The design also features a large, tapered leading edge to deflect pedal strikes on rough terrain. A custom radial seal protects three fully sealed cartridge bearings for low-friction riding in all conditions.
