Stolen Throttle Sealed Aluminum are freestyle BMX pedals with a 9/16" axle diameter, making them compatible with two-piece and three-piece cranks. They are made of durable and reliable metal alloy. The axes are made of durable chromoly steel, which guarantees additional durability. The pedals run smoothly thanks to sealed bearings that are virtually maintenance-free. With large pedal surfaces like these, it's easier to catch the pedals on landing.
