The Tilt Selects i.Shack SCS is a high performance quad clamp designed for stunt scooters. It fits 35mm oversized bars and 32mm regular bars, all thanks to the included shim. With a built-in SCS compression, this Tilt scooter clamp not only keeps your bar fixed, but also functions as a compression system. The Tilt Selects i.Shack SCS is made from aluminium, which ensures a light yet strong construction.
