Shimano SLX M7120 Crankset

No, this specific model is optimized for 148mm Boost spacing with a 55mm chainline. It is designed to work with frames that have wider rear hub spacing, so it will not align correctly on older, non-Boost frames.

This crankset uses the Hollowtech II spindle interface, which requires a 24mm bottom bracket. You will need a Shimano Hollowtech II compatible bottom bracket that matches your frame's shell standard, such as threaded BSA or press-fit options.

While the chainring is optimized for Shimano's 12-speed Hyperglide+ chains, it is generally intended for 1x12 setups. Using it with 10 or 11-speed drivetrains may result in poor shifting performance or increased wear due to chain width differences.

The Q-factor is 178mm. This measurement represents the distance between the crank arms where the pedals attach; a wider Q-factor is necessary to clear the wider chainstays found on modern Boost-spaced frames.

Yes, the SLX M7120 typically ships as a complete crankset including the direct-mount chainring. However, because it uses a direct-mount interface, you can easily swap the ring later if you need to change your gear ratio.

Hollow-forging allows Shimano to remove material from the center of the crank arm where it isn't needed for structural integrity. This reduces weight without sacrificing the stiffness required for aggressive trail riding, making it a reliable choice for demanding terrain.
