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.

- Compatible with 50-tooth Exile Sprotor systems only; the 48-tooth variant has been discontinued and this caliper cannot be used as a replacement for a 48-tooth unit — the caliper mounting arm length is matched to sprocket diameter and the two are not interchangeable
