HED WHEELS Lenticular Disc Standard

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. The HED Standard disc is available in clincher or tubular, 650cc or 700c. Shimano compatible cassette. Weight limit 200lbs. The LI Upgrade Kit includes an upgrade to ceramic bearings for H3, H3C, and Disc.
