Traditional 12-speed systems are great for cadence pedaling, but rough Enduro and Downcountry trails demand something else: instant response, robust performance, and the ability to drop multiple gears in a flash when the trail points down. That’s exactly why we developed the RACEMODD 10-speed cassette.
By reducing the cog count to 10, we’ve created a drivetrain that shifts faster, more precisely, and is significantly more resistant to mud buildup. The upper four largest cogs mirror the SRAM Eagle gear steps, ensuring you lose no climbing ability even on the steepest ascents. The game changes from the middle of the cassette downwards—larger jumps between cogs mean you need fewer “clicks” to set up for a downhill sprint, hitting your heavy gear in a fraction of a second.
Technical Specifications (Total Weight: 358 g):

Upper Cluster (180 g): 4 largest cogs CNC-machined from a single block of premium 7075 T6 aluminum.
-
Middle Cluster (126 g): 3 steel cogs securely riveted to a lightweight aluminum carrier.
-
Lower Cogs (46 g): 3 individual steel cogs for maximum durability during high-torque sprints.
-
Lockring (5 g): Ultralight HG lockring.
-
Chain Compatibility: Runs flawlessly with 10-, 11-, and 12-speed chains.
-
