Does it come with mounting screws?
No, this guard does not include screws. It is designed to be mounted directly onto the quick-release axle of the bike without additional hardware.
Is this suitable for high-end carbon racing bikes?
This guard is not recommended for high-end carbon or lightweight racing setups where weight is a concern. It is best for budget touring, commuting, and casual riding.
