The Shimano Alfine SL-S503 8-speed shifter can be used for the Alfine SG-S501 and for Nexus C6000 internally geared hubs with shifting unit CJ-8S40. Like all Rapidfire Plus shifters it features the 2-Way Release function, so the release lever can be operated by pulling with the index finger as well as by pressing with the thumb. The SL-S503 presents itself modern and sporty and convinces with exact shifting performance. It has an aluminium housing (silver or black) and levers made of synthetic resin and steel. The Alfine shifter is equipped with an easy to read gear indicator and comes complete with cable and SP41 cable housing.
