Origin8 Alloy Chainring Bolts

No, these are specifically engineered for single-speed configurations. They are designed to secure a single chainring to a crankset and will not work with the spacing requirements of multi-speed drivetrains.

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

These bolts are designed for MX/single-speed setups. Before purchasing, verify that your crankset uses standard M8 hardware and that the 4mm inside height matches the thickness of your specific chainring and crank spider.

Aluminum bolts are significantly lighter than their steel counterparts, which helps reduce rotating mass on your drivetrain. While they are durable, they should be tightened carefully with a torque wrench to avoid stripping the threads.

Yes, the set includes five bolts and five matching nuts, which is the standard amount required to secure a single chainring to a typical five-arm crankset.
