Just like any other chainring manufactures, we use 7075-T6 aluminum and then CNC machined them for both high strength and light weight. But after countless analysis and optimization, we can proudly announce the lightest chainring on the market, without any compromise.

We use popular narrow-wide tooth suits for 1X groupset. All the chainring make specific offset to reach the best chainline of your frame.

The rotor has hundreds of small holes on the surface, which means 30% more effective area for dissipating the heat generate during the braking process compared to traditional disc rotors. The bigger contact area for the brake pads also provides a higher brake force. Obviously, it will make your ride safer with lower temperatures rotor and extra brake force.

Probably the lightest steer tube for Lefty in the world. With Toray carbon fiber, the steer tube reaches the best balance between the stiffness and the weight.

Note: Because Ocho does not need a special steer tube, our lefty steer tube is only available on demand.
