Shimano original parts maintain the precision and function of the components for optimum performance, maximum safety and long durability.
QualityThe quality of Shimano original parts is impressive. Every part is extensively tested and inspected. Shimano's internal requirements are often higher than those of industry standards and norms. This brings safety and reliability. Performance The segmentation into groups clearly divides the performance according to the top-down principle. This clearly defines the respective Shimano performance level.
Compatibility Only Shimano original parts fit perfectly to the Shimano components. The optimum accuracy of fit facilitates replacement and meets the highest demands in all respects.

Hollowtech crank and Octalink bottom bracket axle mounts Light cranks reduce the overall weight of the wheel and above all the rotating mass that is crucial for acceleration. The challenge is to reduce the weight of the crank without compromising stability and load-bearing capacity. Shimano's state-of-the-art forging technology provides an ideal solution with the Hollowtech crank. Precisely like a high-quality frame tube, the hollow arm crank handle is extremely stable and resilient at very low weight. The bottom bracket also contributes an important part to the stiffest possible crank. Hollowtech cranks are not connected to the bottom bracket by means of the traditional square cone, but by an octagonal toothing with a larger diameter, which engages the counterpart on the hollow shaft of the inner bearing. This system is called Octalink. This results in a stiffer crank/internal bearing bond.
