Incredible weight savings separates Shimano's XTR components from the pack. These amazing parts often weigh less than half what the competition does while providing greater strength, durability and stiffness. Translation: these are must-spec components for your top-of-the-line off-road rig. Plus, you'll appreciate the precision stopping power of the hydraulic disk brakes, the ergonomic ease of the integrated shifters and the way the stiff crankset turns your bike into a rocket. Whether you're podium-bound or simply need components that can handle long, hard miles, XTR is the way to go.
