XCX Plus Cassettes are an elegant upgrade for any 11 speed Gravel or XC drivetrain. The 9t cog allows for more range in an overall smaller cassette, which means less weight and faster jumps between gears.

Check out the video with Glen from Rodeo Labs, he explains why the 9-39t is their cassette of choice for the Trail Donkey. 

ALL e*thirteen assettes utilize two-piece construction, allowing for individual parts to be replaced as they wear.

XCX Plus 11 Speed Cassettes use 10 steel cogs, and 1 aluminum cog, and the replacement parts are designed for use with 9-34t, 9-39t, and 9-42t XCX Plus Cassettes.

Product Spec

SRAM™ / Shimano™ 11 speed drivetrains
Our 9t cog allows for greater range in an overall more compact and lighter drivetrain. Smaller cogs allow for a smaller chainring, improving ground clearance and reducing the amount of chain needed. Less material, less weight.

Aluminum cluster mounts to an XD™ Driver with a 3mm pinch bolt.

Steel cluster mounts to the aluminum with a standard cassette spline tool.

Removes simply with a chainwhip and cassette tool.

Keeps your drivetrain simple and still gives the gear range of a 2X system.
