Box Components Three Prime Cassette

Yes, as long as your wheel uses a standard Shimano/SRAM HG freehub body. It is designed to be compatible with standard 8, 9, and 10-speed freehub standards, making it a straightforward upgrade for many bikes.

Absolutely. The Box Three Prime is specifically engineered to handle the increased torque and stress loads associated with ebike motors, offering durability where standard cassettes might wear out prematurely.

The Prime 9 system uses larger jumps between gears to achieve an ultra-wide 11-46T range without needing the extra cogs found on 12-speed drivetrains. This simplifies your shifting and reduces the overall weight of your drivetrain.

You will need to pair this cassette with a 9-speed chain. Because the Prime 9 system is designed as a complete ecosystem, it works best when paired with a Box Prime 9 shifter and derailleur.

While the cogs are made from durable steel, Box has incorporated weight-reducing holes and pinned the larger cogs to lightweight alloy spiders to keep the overall mass competitive. It balances the longevity of steel with the weight savings of alloy construction.
