SRAM DUAL DRIVE CLICK BOX 3 SPEED

SRAM's Dual Drive is a unique drivetrain that combines a three-speed internal-gear hub with an external cassette and derailleur. The result is a wide-range of gears in a clean, one handed control system. SRAM's Dual Drive Click box attaches to the Dual Drive hub—and the Dual Drive shifter via cable—so you can shift between the hub's three internal gears.
