The Strummer HR-20 hub set is one of the best hub options for your road bike. Designed to be fast on the road, light on climbs, and tough enough to handle water, dust, and various other conditions. The 4-Pawl mechanism propels the bike forward by steadily transferring power from the pedals to the wheel.
Each hub is precision-manufactured using a combination of AL6061-T6 and AL7075-T6 alloy, then undergoes finishing and anodizing processes according to our high standards. Our range of hubs offers a variety of options and accessories to suit different axle sizes, spoke hole counts, disc brake rotor mounts, cassette sprocket systems, and colors.
