Exile Cycles Sprocket Brake Replacement Caliper for 50 Tooth Sprotor Chopper Bobber
Replacing the caliper on an Exile Sprotor system restores the precise, confident feel that made the setup a signature of serious custom builds in the first place. The two-piston billet aluminum caliper delivers the same controlled stopping performance as the original, and the choice of finish means the rebuilt rear end looks exactly the way it should, purposeful, clean, and unmistakably Exile.
