  • £8.49
  • RRP £18.99
  • Saving you £55

Ready for adventure, this superb component features a robust alloy construction which makes it ideal at handling all the intensity that comes with commuting across the city. Coming equipped with Shimano Index System technology, this brilliant model allows for frictionless shifting and smooth action as you change gear.   Technologies:  Shimano Index System: The system constituents such as the index mechanism built in the shifting lever, the frictionless SIS rear index shifting cable and the smooth action rear derailleur realize the SHIMANO INDEX SYSTEM. Double Servo: SHIMANO’s double servo-panta mechanism enables the rear derailleur to move in an optimum path. The guide pulley tracks the cogs closely while moving front to back, optimizing each shift. Perfect tracking contributes to the most accurate SIS shifting. Keeps rear derailleur guide pulley an optimum distance from each sprocket. Hyperglide: 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 optimization to achieve super-highly efficient shifting.
