Modeled after Shimano's legendary Saint platform pedals, the PD-GR500's give us the same level of performance in a more cost-effective package. Our favorite feature is the height-adjustable traction pins that allow us to raise or lower the pins using the included spacers. This means we can run taller pins for more aggressive downhill runs, shorter pins for urban commutes and trail riding, or anything in between depending on our personal preferences. The PD-GR500 pedals use a low-profile cast aluminum body mated to a chromoly steel axle with sealed cartridge bearings for maximum durability and strength. Three degrees of concave places your foot closer to the axle and improves grip. Its large openings help shed mud so your footing is always secure. The Shimano PD-GR500 Pedals are available in Silver and Black and will survive the park and shuttles for years to come without breaking the bank.
