The second generation of the innovative reel-changing system lets you tailor the throttle rate to riding conditions and rider preference. New ultra-compact housing with snap-together elbows make it easy-to-install and change reels. Sleek new design requires less handlebar space for lever clearance and throttle position. Use smaller reels for slower throttle rate and larger reels for faster throttle rate. Included cam reel provides progressive throttle response preferred by some riders. Unique reel design allows fast reel changes. Cable boot keeps dirt and dust out for reliable and smooth operation. Billet aluminum in-line cable adjusters for easy installation and adjustment. Lower section of cables use 5mm housing with PTFE liner for reduced friction, increased routing flexibility and lighter weight. Upper section of cables use 6mm housing to provide solid support of adjusters. Simple to install and maintain.
