Shimano XT FC-M8120 12 Speed Front Crank - 170mm

The Shimano XT M8120 series cranks are built to handle everything you can throw at them.

By utilising Hollowtech II technology Shimano is able to keep the weight down, while still creating a rigid crank arm capable of handling some seriously aggressive trail riding.

The M8120 cranks are compatible with Boost frames only.

Technologies

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 maximize a rider's power transfer. The rigidity of the crankset ensures pedaling 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. HollowTechtechnology 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 a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling 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.

High Precision Sealing

Moreover, HollowTech II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.
