Brake modulation separates competent descenders from confident ones. The G2 RSC sits at the top of SRAM's Guide-replacement lineup, built for trail and enduro riders who want precise lever control without the price tag of Code brakes. The "RSC" designation indicates the full feature set: Reach adjust moves the lever blade closer or further from the bar, SwingLink technology creates a smoother lever feel through an intermediate linkage, and Contact Point adjustment lets you dial where in the lever stroke the pads meet the rotor.

The lever body uses aluminum construction with tool-free reach adjustment accessible from the cockpit. SwingLink's mechanical advantage curve delivers consistent power throughout the stroke rather than an on-off feel, which matters when you're modulating speed through loose corners or technical rock sections. Contact Point adjustment requires a 2.5mm hex key and moves the engagement point without affecting total lever travel—useful for riders who prefer pads riding closer to the rotor or those who want more free stroke before engagement.

SRAM pairs the G2 RSC lever with their S4 caliper, a four-piston design that replaced the older two-piston Guide calipers. Four pistons distribute clamping force more evenly across the pad surface, reducing the likelihood of uneven wear and improving heat management during extended descents. The caliper accepts SRAM's Centerline and Centerline X rotors in 160mm, 180mm, and 200mm sizes depending on your frame and fork compatibility.... Read More
