Proprietary actuation ratio with 'Yaw' cage-angle shift technology that tracks with chain eliminating the need for shifter trim (only compatible with Red22 SRAM road shifters and cranksets)
Hybrid construction with shift-engineered alloy-outer/steel-inner/composite-tail cage optimized for X-GlideR chainrings in traditional and compact gearing
Includes optional and independently adjustable Chain Spotter that integrates with mount to eliminate chain drop and resulting frame damage
Braze-on design can be used with SRAM adapter clamps to fit 31.8/34.9mm frames if needed (available separately in derailleur parts)
