Increased rigidity with less weight. Wider bearing positioning. Rigidity is enhanced and pedalling force is efficiently transmitted. Precision Bearings. Low maintenance and simplified installation. HG HyperGlide Compatible: 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. Hollowtech II: Providing the best balance of stiffness, strength, weight and rotating performance, 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 weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. Hollowtech technology is an ultra-lightweight hollow crankarm created by Shimano with the company’s own proprietary forging technology that also maintains rigidity.
