This superb model is specifically designed for MTB use as it features special gear teeth which improve chain engagement & retention. in addition, its hollow forged alloy cranks maximise your power transfer while also keeping its overall weight reduced. This excellent strength to weight ratio means you can shred the trails in style without having to worry about adding any unnecessary weight to your ride. This is the ultimate choice of upgrade for enjoying a smoother & highly efficient off-road riding experience. Technologies: Dynamic Chain Engagement+: Dynamic Chain Engagement+ is a special gear teeth profile designed for use in single-chainring configurations for XC, enduro, & trail riding. It gives more chain retention & smoother pedalling
- even over bumpy terrain. Chain retention of any gear will reduce abrasion & worn out. Hollowtech II: Providing the best balance of stiffness, strength, weight & 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. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness & weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution & more pedalling stability, allowing for more efficient power transfer. The Hollowtech II crankset has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight & beautiful crankset design. Moreover, Hollowtech II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.
