Strummer HR-20 Ratchet is one of the best hubs you can get for your road bicycle with rim brake mechanism. Designed to be fast on the road, quick in corners, lightweight on climbs, and durable enough to resist water, dust, and other elements that might come in its way. Driving the bicycle forward is a 36T ratchet mechanism, providing 10° degrees of engagement & solid power transfer from your pedals to your wheels.
This ratchet mechanism can be further upgraded to 60T, resulting in quicker response when pedaling from a stop. 60T star ratchet upgrade will improve degrees of engagement to an astonishing 6° degrees.
Every single hub is precision manufactured with a mix of AL6061-T6 and AL7075-T6 alloy, finished, and anodized to our high standards.

Innovation, Since Day One
Since our inception in 2008, we strive to make better products that can be depended on. Starting with our CAD technology. Our headsets remove unnecessary clamping to fork axle while providing identical performance. We are also one of the first to sell convertible hubs in Indonesia.
Pay Attention to the Details
We obsessively focus on the details. Improving by the millimeter. Adding the stiffness of our hubs by widening the flange of our hubs, thus increasing wheelset stability and strength.
