It embraces range without adding complexity. The outcome is fewer parts, reduced weight, and increased durability. Fewer parts, reduced weight, and increased durabilityPrime 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 cassetteThe 2-piece multi-shift pull lever allows for riders to move up to 3 gears per shiftThe Prime 9 chain is compatible with modern narrow/wide chainrings, and resists stretching over time, and decreases wear on the cassette and chainring
