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.

Rapidfire Plus
Rapidfire Plus has been used by mountain bikers since 1985. Rapidfire Plus is still the first choice for a wide range of rider groups, from Cross Country racers to freeriders and downhillers. Rapidfire Plus is suitable for fast shifting.

2-Way Release
All newer Rapidfire Plus shift levers are equipped with 2-way release (release in two directions). This means that the shift cable is released by pulling with the index finger or pressing with the thumb.
