Jagwire&';s Cable Grips are adapters that make it possible to run hydraulic brake lines on bicycle frames that have housing stops that were designed for regular wire cables and standard housing sections. Once the regular cables and housing sections are removed, the Cable Grips are inserted and tightened in place in the standard frame stops. Then, the hydraulic lines are attached and securely held in place by the gripping jaw(s) of the Cable Grips. - Aluminum model accepts lines up to 5mm in diameter and the lines snap in. - Stainless model grips fully around the lines and is adjustable to fit most diameters.
