Product details

The Strummer HR-10 4-Pawl hub is designed for cyclists who want smooth and efficient wheel rotation without compromising durability. Equipped with a 4-pawl system, this hub offers an optimal engagement angle (responsive enough without being excessive), helping maintain speed while coasting. With HG cassette system compatibility, this hub can be paired with various sprocket cassettes and groupsets. In addition, it supports HG road sprockets up to 12-speed, providing greater flexibility for various types of bicycle components.

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.

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.
