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 convertable hubs in Indonesia.


Focus on 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.
