Shimano SLX FC-M7120 1x Crank Arms

Why We Like The SLX FC-M7120 1x Crank Arms

In the world of Shimano, trickle-down tech means these SLX FC-M7120 Crank Arms are the beneficiary of years of testing on higher-end drivetrains. Built tough for years of use, these SLX Cranks use the exact same chain retention system and technology as its higher-end cousin, but at a fraction of the cost. We’ll put these on our bikes and forget about them year after year of top-quality drivetrain performance.
