Shimano SLX FC-M7120-1 Crank 1x12-speed - Boost

Shimano SLX FC-M7120-1 Crank 1x12-speed - Boost

Just as mountainbiking and its riders are constantly evolving, Shimano is permanently striving to provide athletes with innovative materials for an unprecedented riding experience. The SLX M7100 series has been developed for these mountainbikers who want to explore new adventures and adapts - typically Shimano - the technologies of the high-end XTR group. These innovations include 12-speed drivetrain, Micro Spline and Hyperglide+ which have already proven themselves on Deore XT series.


Shimano SLX FC-M7120-1 crank

Like its Deore XT counterpart, the SLX FC-M7120 1x12-speed crank relies on a solid and nevertheless lightweight design thanks to its hollow forged crank arms. For a quick and secure chainring installation the Hollowtech II crank features a Direct Mount system.

In combination with the Shimano SM-CRM75 chainrings with Dynamic Chain Engagement+ technology (sold separately), the FC-M7120-1 crankset holds the chain safely even on rough terrain and guarantees at the same time an efficient, smooth and quiet drivetrain.
