The PD-MX70 DXR Pedals are Shimano's first SPD pedals that are tuned specifically for BMX Racing. Following in the footsteps of the winning DXR component line, the new PD-MX70 pedals have been tested and raced at every level from the local start gate to the Olympic track. Factoring in the high pedaling forces of BMX racing, these pedals feature a dedicated high-retention mechanism that prevents unclipping under extreme upward pedaling force as well as a narrow, 9-degree release angle and 2-degree float for a more fixed and stable feeling. The integrated cage is the same one used on Shimano's trusty XT M8020 pedals, improving control when you're not clipped-in and protecting the binding mechanism from impact damage.
