The Prime 9 range of components from Box has made many people rethink what a 9-speed drivetrain is capable of. Providing riders with all the range of a 12-speed setup but without the complexity, weight, and excessive shifting, Prime 9 drivetrains are also far more affordable. You can ride them hard and not shed so many tears when something inevitably wears out or breaks.Box Three is their best all-rounder drivetrain that offers excellent performance and durability at a wallet-friendly price point.Single-shift groupsets have been designed with e-bikes in mind and feature a 12T smallest cog rather than the 11T found on the multi-shift options.Who's this item for: This is for riders looking for all the same range as a 12-speed setup with the simplicity and weight savings of a 9-speed setup. It's a great choice for those wanting to bring an older 2x/3x drivetrain bike into the 12 century without needing to re-mortgage the house.Compatibility: Single-shift groupsets have been designed with e-bikes in mind and feature a 12T smallest cog rather than the 11T found on the multi-shift options.All Prime 9 components are cross-compatible with other levels across the range.
