Overview
Not a road crank, this Acera FC-M361 is a mountain bike crankset that turns a chain drive through three chainrings. Replaceable rings and shifting guides are built into the design, so worn teeth do not mean replacing the whole arm set.
The three chainring layout gives a wide gear range for climbs and descents on mountain terrain, and the replaceable rings are a real maintenance advantage. The spec fields contain obvious errors such as a battery power source, so trust the size and description rather than those rows.
Who it's for
Mountain bikers running a seven speed chain drive who want a straightforward triple crankset will find the fit clear. Owners of ten or eleven speed drivetrains should look elsewhere.
Pros and cons
- Shifting guides aid chain transfer
- Wide gear range from three rings
- Mountain bike intended
- Bottom bracket not mentioned in listing
- Several spec rows contain obvious errors
- Seven speed only
- Older 2012 model year
Performance notes
Shifting guides on the rings lift and catch the chain during a gear change, which smooths transfers between the small, middle and large rings. A longer crank arm gives more leverage per pedal stroke, and the triple layout lets a rider drop to a very small ring on steep climbs.
