Compatibility, Size and Fit
This crankset is described for single speed bicycles and MTB bikes with 7 to 12 speeds. The key fit checks are the 104 mm BCD, the 170 mm crank arm length and the 68 to 73 mm bottom bracket width. Those are the main measurements to compare against the bicycle you want to fit.
Because several configuration options are listed, confirm the exact version before choosing an offer, especially if you need the bottom bracket, the chainring, or both included.
Before You Decide
Check the 104 mm BCD, the 170 mm crank arm length and the 68 to 73 mm bottom bracket width before choosing. Confirm whether you want the crank only or the version supplied with the bottom bracket and 32T chainring. If speed compatibility matters, compare the stated single speed and 7 to 12 speed range with your bike.
Follow the manufacturer instructions for fitting and setup.
