Box Three Prime 9 Multi-Shift Groupset X-Wide

Box’s Prime 9 Technology is a counter-intuitive philosophy based on the less is more theory. It embraces range without adding complexity. The outcome is fewer parts, reduced weight, and increased durability. Prime 9 technology offers the same range as a 12-speed drivetrain, with fewer gears to shift through. Fewer parts, reduced weight, and increased durability. Prime 9 drivetrains significantly reduce the chain angle in the lowest gears, allowing the chain to run straighter across all gears, increasing the life of the chain and cassette. The 2-piece multi-shift pull lever allows for riders to move up to 3 gears per shift. The Prime 9 chain is compatible with modern narrow/wide chainrings, and resists stretching over time, and decreases wear on the cassette and chainring. The x-wide rear derailleur features a limited slip clutch, which engages instantly with constant torque for less chain slap, better chain engagement and no dropped chains. The 11-50t cassette offers ultra-wide ratio with consistent progressions. Item Specifications: , Weight1354 g, Cassette Cogs11-13-16-20-24-30-36-42-50,
