TRP's Hylex RS is a full hydraulic single-speed disc brake system designed for road and CX bikes. It is built for single-speed aficionados who want simplicity without sacrificing braking performance. The lever features ergonomic and perfectly sized hoods that create a natural extension from the rider's hands to the bike. It has an integrated master cylinder within the low-profile, ergonomically shaped lever body, while the drilled-out lever blade helps reduce weight and improve grip.
