The Rocket 3 Crankset is a modern 1x crank featuring a direct mount chainring and adjustable tension on the BB bearings. The arms are forged from AL7075, heat treated to a T6 hardness, then shot peened to compact the surface structure. The cranks are then hard anodized and laser etched before the spindle is pressed in. The spindle is 24mm high strength Cr-Mo steel, and is splined for adjustability and easy service. The non-drive arm features dual opposed pinch bolts with an endcap to adjust tension on the angular contact bearings in the bottom bracket. They can be ordered with standard chainrings, or boost (+3mm offset) for 148mm rear hubs. Though these cranks are lightweight, they are strong and stiff for direct transmission of force to the rear wheel. Available in 165mm, 170mm, and 175mm arm lengths.
