The Manual brake cable is about as tech as a cable gets. with its spiral shell casing that ensures durability and consistent brake feel when wound up for tailwhips or barspins. an inner stainless cable with Teflon coating for flawless performance and the smoothest pull possible. Literally capping things off. two very unique aluminum CNC machined cable ferrules that have an internal cone shape that not only pushes the outer cable away from the inner cable to ensure zero bind. but also helps avoid �cable blowout� where the outer cable potentially pushes through a conventional ferrule. found only on Manual brake cables.
