In developing the HR-10 hub, we investigated the factors that affect smooth rotation with minimal resistance. One of the main aspects we identified was the use of high-precision bearings. In addition, the hub body’s design and quality also play a crucial role.
We use high-precision CNC machining, one of the best in its class, to ensure that the bearings are installed without excessive pressure and that pressure is distributed evenly from all sides. Strummer’s CAD (Center Alignment Design) technology further refines this balance, ensuring that the bearings are installed precisely at the center of the hub body according to our strict standards.

| Freehub Body | 15267-2RS | 15 × 26 × 7 mm | 2 pcs | LAHAR-00012 | LAHAR-00014 |
Match the code, dimensions, and seals with the old bearing before purchasing. Hybrid Ceramic is an upgrade option if the type and size are suitable.
Rear Hub (Freehub) Maintenance Notes
Grease lubricates the parts that come into contact in the freehub mechanism of the rear hub, helping reduce friction and wear. We do not recommend removing all the grease solely to achieve a louder sound. Without adequate lubrication, components may wear out or become damaged more quickly, shortening their service life. Use the type and amount of lubricant recommended for product maintenance.
