Ferrules are one of those small parts that get overlooked until a cable job goes wrong — a missing or crushed ferrule means the housing seats poorly, compression happens under load, and your brake feel goes soft. SRAM's Pit-Stop Brake Cable Ferrules are 5mm open-type ferrules for brake cable housing, the profile used with exposed cables rather than fully sealed setups. This 10-pack is enough to cover a full brake cable replacement with spares left over for the parts bin.

The 5mm inside diameter matches standard brake housing across the industry, so these work on SRAM, Shimano, and Campagnolo mechanical brake systems — anywhere you're running traditional 5mm coiled or linear-strand brake housing. The open profile leaves the cable exposed as it exits the housing, which is what you want for standard mechanical brake setups where the cable travels through frame stops or barrel adjusters between housing sections.

If you're doing a full cable and housing replacement, you'll typically need four ferrules per bike — one at each end of the front and rear housing runs, minus any that seat directly into a brake lever or caliper barrel adjuster. A 10-pack gives you a full job with backups, or covers two full replacements. Keep in mind these are brake-specific at 5mm; shift housing uses 4mm ferrules and isn't interchangeable.
