XTR. Those three letters represent the very best, the pinnacle of mountain bike technology. Since its debut XTR has been the absolute standard for lightness, durability and performance. XTR is the benchmark by which all other off-road components are judged. And they've just moved it up again.

The new XTR isn't just a refinement of what's come before - it's an almost total overhaul that completely changes the riding experience. Ride with quicker, faster control and response, anywhere you want. Whether you're a cross-country racer, an all-mountain rider or just someone who wants the very best, new XTR is engineered for the way you ride.

A three piece aluminum carrier and 4 titanium cogs make the new CS-M970 Shimano's lightest 9-speed mountain bike cassette ever. Compatible with any 8 or 9 speed HG compatible rear hub.
