RD-420

It’s time for you to discover the World’s only round section rim. Why round? It’s the best combination of ride quality and rigidity. In particular, torsional rigidity of a rim skyrockets with cross sectional roundness, increasing as the 4th power of the diameter! Torsional rigidity is what keeps a wheel from becoming a taco. 

The round rim section, actually a 20mm tube, is much harder to produce than other shapes. But once we succeeded, we found an amazing combination of smoothness, supple response, and stability.
