Q. What is a POP Ferrule and how is it used?
A: POP ferrules are used to cap brake housings in Jagwire’s Ripcord cable kits and some Racer kits. It’s used specifically on the trailing end of the housing where it meets the brake. It’s a critical part for V-brakes; the POP inserts into the brake noodle to reinforce the noodle.. For mechanical disc brakes and road caliper brakes the POP can be used, but may not fit properly; in this case we recommend terminating the housing using a standard alloy end cap.
