What to Compare Before Buying
- Front or rear use: This set is described for tandem road front or rear use. Confirm which position you need on the bike.
- Spindle interface: The stated spindle type is 134 mm JIS square taper. Match that to the crank interface on the tandem setup.
- Crankarm length: The length is 170 mm. Compare that against your preferred fit and riding position.
- Chainring size: The included chainring is 39 teeth. Check that this matches your drivetrain needs.
Before You Decide
Confirm the tandem position you need, the 134 mm JIS square taper interface, and the 170 mm crankarm length before choosing an offer. If chainring size matters, also check the included 39-tooth chainring.
Additional Drivetrain Fit Checks
Beyond the crank interface, confirm that the crankset’s chainline and the chainring mounting pattern suit the existing drivetrain. These fit details are not established by crankarm length or tooth count alone.
