Do you know aero spokes were once unknown? Sounds unlikely, they’re so fundamental to today’s wind slaying cycling. Modern aero spokes begin with Claude Lehaneur’s, in his visionary Roval wheels of the late 1970’s. That work deserves a chapter of its own. Coming. The mass appearance of aero spokes coincides with technical excitement running up to the 1984 Olympics in Los Angeles. Never before was such a concentrated effort made in the USA camp to quantify and optimize the design features of racing bikes. Francesco Moser had just set an hour record on oversized disk wheels. The Pandora’s box of aerodynamic tricks was opening.
