LeMond won a minute in the time trial in stage five, using aerobars which enabled a new and more aerodynamic riding position (also known as tri-bars as they had previously only been used in triathlons), a new type of teardrop-shaped aerodynamic helmet in the time trials and a rear disc wheel, Fignon used normal road handlebars and a bicycle with both front and rear disc wheels, which left him more affected by cross winds.
