This rigid and lightweight model delivers a smooth driving experience as you weave your way around the trails, even when riding over rowdy terrain conditions. Its 36 to 26 tooth ratio provides an extra wide range for more simple gearing than racing groupsets. Furthermore, its forged aluminium crank arm construction and steel inner chainring deliver a top-level strength to weight set-up. This is the perfect choice of upgrade for completing your dream bike build and getting the best performance out of every off-road adventure.
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. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and 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 and 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.
