Shimano have designed the SORA derailleur for sporting cyclists who ride for fitness.
Its stylish, clean, robust design combined with technology that Shimano has adopted from their higher level groupsets, resulting in the comfortable feel of a light action for low friction shifting that a 9-speed can offer - perfect whether you are a fitness enthusiast or a newcomer to the sport of riding.
HG Sprockets - The distinctively designed HyperGlide sprockets incorporate specially positioned shift ramps and tooth profiles for improved chain control during shifting. Fast and responsive indexed shifting is the result. The HG cassette sprocket, which was developed for the MTB 10-speed system, underwent comprehensive optimisation to achieve super-highly efficient shifting.
