Halo Fixed Gear Lockring

This lockring uses a standard 1.29" x 24tpi left-hand thread, which is the industry standard for the vast majority of track and fixed-gear hubs. However, it will not fit hubs with proprietary or non-standard threading, so it is best to verify your hub's specifications before purchasing.

Yes, you will need a standard two-prong lockring tool to properly tighten this component. The two-dog design is specifically engineered to interface with these common tools, ensuring you can achieve the necessary torque to keep your cog secure.

Fixed gear hubs use a left-hand thread for the lockring to prevent the cog from unscrewing while you pedal or apply back-pressure to brake. As you ride, the natural forces on the drivetrain actually work to tighten the lockring against the cog, keeping everything secure.

The chrome plating provides a durable, corrosion-resistant barrier that is significantly more robust than raw or painted steel. While it is highly resistant to the elements, keeping your drivetrain clean and lightly lubricated will ensure it stays in top condition for years.

Yes, as long as the threads on the lockring remain clean and undamaged, it can be reused. However, if you notice any stripping or deformation on the threads or the two-dog notches, it is safer to replace it to ensure your cog doesn't come loose while riding.
