WebDec 1, 2024 · 1. Introduction. In cycling jargon, drafting is a riding technique whereby a cyclist closely follows the preceding athlete, thereby substantially reducing the aerodynamic drag (Barry et al., 2015; Blocken et al., 2024; Broker et al., 1999).Already in 1953, Kawamura conducted wind tunnel measurements of two ¼ scaled cyclist models in … WebNov 23, 2024 · CdA and Aerodynamics of Cycling. November 23, 2024. Photo courtesy of SnowyMountain Photography. Seventy to ninety percent of the opposing force you face as a cyclist on a flat road is aerodynamic drag. Most of us have felt the experience of drafting before, or even a tailwind versus a head wind. This is the greatest drag we face on the …
