Materials & Durability
Constructed from high-quality materials, the BOX Prime 9 groupset features a lightweight yet robust build. The wide rear derailleur is equipped with a limited slip clutch, which engages instantly to minimize chain slap, enhance chain engagement, and prevent dropped chains-ensuring smooth operation in even the roughest conditions. The Prime 9 chain is resistant to stretching, promotes drivetrain longevity, and is fully compatible with modern narrow/wide chainrings for reduced wear.
Performance & Engineering
Prime 9 technology redefines shifting by offering an ultra-wide gear ratio of 11-46t with just nine gears, providing the same range as a 12-speed setup but with simplified operation. The drivetrain's design minimizes chain angles, especially in low gears, allowing the chain to run straighter across all gears. This results in increased chain and cassette lifespan, improved power transfer, and reliable shifts in every riding scenario.
