Compatibility, Size and Fit
Confirm that the bike uses a single-speed drivetrain and has a compatible square-taper interface. The 104 BCD refers to the chainring’s bolt circle diameter, so check that the mounting pattern matches. The listing does not provide further bottom-bracket or bike-fit details; verify those against the bike’s specifications before choosing this part.
What to Compare Before Buying
- Drivetrain: This crankset is specified for single-speed use, not other-speed drivetrains.
- Crank length: Compare the 170 mm arms with the length required for the bike.
- Mounting fit: Check both the square-taper interface and 104 BCD pattern against the existing setup.
- Chainring: Confirm that a 30T ring and its narrow-wide profile suit the intended single-speed configuration. The listing says the tooth design can help prevent chain drops; it does not guarantee that a chain will stay on.
Before You Decide
Check the single-speed restriction, 170 mm arm length, square-taper interface and 104 BCD fit. Also confirm that the stated chainring and bolt contents match the configuration you need.
