The FC-M371 is a dependable 3x9-speed triple chainset from the brand's Altus range, a popular choice for trekking, hybrid and entry-level mountain bikes. The 44-32-22T rings give a very wide spread of gears, from a low granny ring for steep climbs to a 44T outer for quicker riding on the flat.

Aluminium arms are paired with hard-wearing steel chainrings, and it fits a square taper bottom bracket in a standard 68 or 73mm threaded shell. This version comes without a chainguard.
