Important Notes
Please choose the correct specification according to your chainring and crankset thickness.
Do not exceed the maximum installation torque of 20 Nm.
Manual measurement may result in slight size deviation.
The specification name refers to the nut height, not the total bolt length.
Different chainring and crank setups may require different bolt lengths.
Do not force installation if the bolt length is not suitable.
Aluminum alloy bolts are lightweight parts. Please install carefully and avoid over-tightening.
