Origin8 Alloy Chainring Bolts

No, these are specifically designed for single-speed cranksets. The bolt and nut lengths are optimized for a single chainring setup and will not provide the correct fit or spacing for double or triple chainring configurations.

You will need a standard chainring bolt tool to hold the nut in place and a 5mm hex key (Allen wrench) to tighten the bolt. Using the proper tool prevents the nut from spinning while you tighten the bolt.

Yes, these are made from AL6061 aluminum, which offers a great balance of lightweight performance and strength. They are perfectly suitable for standard single-speed riding, commuting, and light trail use.

While not strictly required, applying a small amount of medium-strength thread locker (like blue Loctite) is a good practice. It helps prevent the bolts from vibrating loose over time due to the constant torque of pedaling.

Yes, these bolts are designed to fit the standard mounting holes found on most single-speed cranksets, including the common 104 BCD pattern. As long as your crankset uses standard M8 chainring hardware, these will be compatible.
