Shimano Tiagra 4700 10 Speed Chainset Chainsets
  • £94.99
  • RRP £109.99
  • Saving you £14

This road bike chainset takes many features from Shimano's pro-level components such as the 4-arm crank and the grey anodised finish delivering reliable rotative performance in all weather conditions. The Shimano Tiagra 4700 10 speed chainset balances weight and efficiency without sacrificing stiffness.  The Shimano Tiagra 4700 10 speed chainset is designed to work with HollowTech II type bottom bracket cups. Technologies: Hollowtech II: The concept of Hollowtech II technology is focused on producing a superior crankset, which will maximise a rider’s power transfer. The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. For most frames, Hollowtech II with its 24mm axle can set the bearing position outside of the frame to provide better weight distribution and more stability. Hollowtech II bottom brackets also have high-precision seals to increase durability, maintaining excellent rotating performance for long periods
