Spare Replacement Part Only
This is a spare 9-30T lower 10-cog block of steel cogs which includes the exclusive-to-ethirteen 9-tooth cog. The 9t sprocket allows you to run a smaller chainring for better ground clearance and additional weight savings.
Restore Your Drive
With this spare part, you can replace the 10 small cogs of your XCX Plus cassette and restore the unrestricted performance of your drive.
ethirteen 2-Piece Cassettes
All ethirteen cassettes come in two pieces. The lower block is steel and the upper cog (or two in the case of 12 speed) is aluminium. They are available separately so that if the parts wear out you can replace the individual components without having to buy a complete new cassette.
Compact and Lighter Drivetrain
For a Gravel or XC drivetrain looking for quick shifting and wide range. The 9t cog allows for more range in an overall smaller cassette, which means less weight and faster jumps between gears.
