Precise shifting. The Shimano Alfine SL-S503 8-SPEED Shifter utilizes RAPIDFIRE Plus technologies for fast and accurate shifting. It is intended to be used in conjunction with an internal 8 speed hub such as the Shimano Alfine on commuter and recreational pavement bikes. Stainless steel cable and housing is included.
Great alternative to the bulkier brake/shifter combo. Used successfully in conjunction with a Nexus 8-speed hub (model SG-8R36), so to all who wonder if this Alfine shifter works with Nexus 8-speed hub, yes it does. Wire was too long for my setup, but easy to shorten, just like a regular derailleur cable.
