BOX Three Prime 9 X-Wide Multi Shift Groupset - X-Wide Rear Derailleur, 11-50t Cassette, Multi Shift Shifter, Prime 9 Chain

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
