This axle reducer is designed for the Ethic DTC 12 STD fork and allows you to use a fork with a 12 mm axle hole together with a wheel that has an 8 mm axle.
It’s a practical solution if you want to keep your existing wheel or bearings and avoid replacing the entire front end. The high-strength steel construction handles load well, and the fit is precise, so this is not a temporary workaround but a proper, purpose-built conversion part.
The package includes 2 spacers, meaning you get a complete pair required for fork installation.
