Shimano Deore M442 Chainset

This is a competitively priced, tough, 9 speed off-road chainset that is compatible with Mega9 and 9 speed drivetrains.
It has hardwearing and slick shifting Steel chainrings and a rigid four-arm chainring mount that reduces weight.
It also has forged aluminium crank arms, for strength and rigidity, that are designed to fit a square tapered-style bottom bracket axle.
