Description

The SHIMANO XT FC-M8120-B2 2x12V Crankset features an entirely new construction, combining direct-mount chainrings and a special tooth profile for improved chain retention.

Its hollow forged-arm HOLLOWTECH II technology maximises power transfer while limiting weight, for a stiff yet lightweight design suited to demanding trail riding. Single or double chainrings can be interchanged as required.

Designed for Boost (148 mm) spacing, it has a Q-factor of 178 mm and a 51.8 mm chainline, with a 36-26T double-chainring gear range.
