Built to withstand the rigors of e-bike riding, the BOX Two Prime 9 e-bike cassette is built with high gears that have more teeth and offers the range of a 12-speed without the added complexity.
- BOX Prime 9 technology offers the same range as a 12-speed drivetrain with fewer gears to shift through, reducing parts and weight while increasing durability
- Adding an extra tooth to each of the 3 highest gears provides increased durability and decreased wear by distributing the load over a larger area
- All cogs are stamped from steel; larger cogs are pinned to lightweight alloy spiders
- Offers ultrawide ratio with consistent progressions
- ED Black finish delivers extra protection from the elements
