The Brake Seat Covers fit the C-Raider, Raider and Crest models (but not the Evo models) and are designed to fill-in the recess in the heel base should the user wish to use the bindings with the brakes removed. A single brake lever has a nominal weight of 43g and a single cover weighs 3g so a 40g net weight saving can be achieved.
Weight = 3g each
