• Exact Actuation™ for fast and accurate shifts using SRAM’s 1:1® actuation ratio (shifter cable travel : derailleur movement)
• X-Sync™ pulley features a 12-tooth design that helps control the chain’s lateral movement
• Roller Bearing Clutch™ controls chain tension for consistent shifting
• X-Horizon™ straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force
