FAQ
Q1: How do I know if this bicycle bottom bracket nut fits my bike? A1: Most universal cranksets use M8 or M10 nuts. We recommend measuring your existing bolt or checking the crankset manual. Our bicycle bottom bracket nut is designed to fit most standard square taper or hollow axles.
Q2: Does the serrated flange damage the crank arm surface? A2: The serrated flange nut bicycle is designed to bite slightly into the surface to create a mechanical lock. While it may leave minor marks, this is a standard safety feature to prevent the crankset locking screw from loosening during rides.
Q3: Is professional tools required for installation? A3: A standard socket wrench or a specialized bottom bracket tool is recommended. Proper torque settings are crucial for the long-term stability of the crankset locking screw.
