Polisport levers represent the evolution of the concect of "flexible levers". The lever is made of a hybrid structure composed by a stainless steel core coated by a proprietary compound called APT (Aero Parts Technology). The APT is a thermoplastic material that simulates the feel and touch of OEM aluminium levers. Thanks to the stainless steel core, the levers can be bent and restored to their original shape without them breaking.The lever adapter is CNC machined aluminium; the pivot system allows the lever to fold outward to prevent breakage in case of fall. Polisport guarantee a lifetime warranty for te hybrid lever (not the CNC machined adapter). Available in the relevant colour of the bike, in white, black, nardo grey or gold. Sold in pairs.
