Overview
Bolting a single steel chainring and a pair of alloy arms onto a drivetrain is what this crankset does. Plastic chain covers are fitted on both sides of the ring.
The title offers three chainring tooth counts, and the color field marks this one as the smaller option. It targets single speed setups and six to eight speed drivetrains. Fitment data is thin.
Who it's for
Commuters and e-bike owners swapping a crankset on a single ring setup are the audience. Riders on double or triple chainring drivetrains need a different part.
Pros and cons
- Aluminium alloy crank arm
- Double chain cover
- Single ring simplicity
- Bottom bracket and bolt circle details not listed
- Tooth count shown in a color field
Performance notes
Tooth count on the chainring sets the gearing against the rear sprockets, and the arm length sets pedal leverage. A steel ring resists tooth wear, while the alloy arm holds weight down.
