The Superlight retains the key characteristics of the standard HED disc, but is lighter. Weight is saved from the aluminum rim by an advanced process of chemical etching.

Wind tunnel testing at the Texas A&M facility has proved the disc to be the most aerodynamically efficient of all the HED wheels. This has also been corroborated by independent tests at Bath University England, which confirmed the advantages and benefits that a lenticular disc has over flat discs. The lenticular shape smoothes the disturbed air produced by the rider and crosswinds, so airflow leaving the wheel surface is less turbulent than on a flat disc or wire spoked wheel. A reduction in turbulence is an increase in speed.
