HG CS-M8000 Cassette

What Our Gearhead® Experts Are Saying:

"I’ve run the CS-M8000 on everything from an XC hardtail to a gravel conversion and it’s always dialed. The gear spacing feels intuitive, and the 11-42T version has enough range to tackle steep climbs without a giant jump between gears. It’s lighter than it looks and still holds up to hard riding."

The Shimano HG CS-M8000 Cassette was built with versatility and precision in mind, offering riders a lightweight yet rugged 11-speed option for demanding trail and gravel applications. Its blend of high-wear steel cogs and a lightweight aluminum carrier keeps weight in check without sacrificing long-term durability.

Engineered with Rhythm Step gear progression, the cassette provides smoother transitions between gears, making it easier to maintain ideal cadence over technical terrain. Riders can choose between 11-40T, 11-42T, or 11-46T ranges depending on their terrain and gearing preferences—ideal for both 1x11 and traditional 2x setups. Installation is straightforward with HG freehub compatibility, and the cassette interfaces seamlessly with both Shimano and SRAM 11-speed derailleurs.

Perfect for everything from trail bike builds to gravel 1x conversions, the CS-M8000 brings together wide gearing, reliable shifting, and proven Shimano performance in a lightweight, trail-tested package.
