A three piece aluminum carrier and 4 titanium cogs make the new CS-M970 Shimano's lightest 9-speed mountain bike cassette ever at 224g. The Shimano XTR group has never outgrown its original design philosophy of delivering top-level performance in a lightweight, beautifully-engineered package. The next generation of XTR raises the bar again in reduced weight, increased stiffness, and improved durability.
- 224 grams
- The top 4 cogs are titanium which reduce weight and extend durableness
