Shimano's heralded XTR moniker promises genre-defining performance, weight, and style. Shimano's XTR Hollowtech II Race Crankset lives up to the name. The hollow, cold-forged aluminum crankarms are ultra light, yet exceptionally stiff for awesome power transfer and efficiency. Front shifts are remarkably fast, clean, and precise, with Shimano's legendary chainrings and computer-designed shift ramps. And to conquer the most heinous climbs, this three chainring setup offers Shimano's widest-range gearing.
