Features

Designed to meet the highest level of competitive mountain bike racing needs, with second to none performance and experience, Shimano XTR M9100 brings lightweight, high-end versatility to XC, enduro, and marathon racing.

Balancing stiffness and power transfer against overall component weight is a chief concern for any crankarm design. Shimano's 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 24mm diameter, outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer.
