In BMX racing, that first sprint from the gate is the most important part of the race. Shimano knows this, so their DXR cranks are unbelievably stiff, perfect for getting out in front for the holeshot. They borrow Hollowtech II technology from the Saint downhill cranks to make them rigid, light and super tough. They sport a narrow Q factor for smooth pedaling and steel pedal inserts for durability. When 2nd place just won't do, DXR is the answer.
