Jacquie Phelan (born December 10, 1955, in San Francisco, California) is an American road and cyclocross racer, and was the NORBA champion three consecutive years—1983, 1984, and 1985.
The roller cam brakes, two chainrings (44-34), and custom-fabricated eleven-tooth rear cog gave a boost in technical riding.
The bike also drew criticism from traditional framebuilders, who believed durable frames had to be made of steel.
Phelan once had the opportunity to ride with Independent Fabrication's racer Amy Crawford, a defining experience for both riders.
In summer 2009 she took part in a two-month vodka commercial called the 42 Below ride, a 4,200-mile crossing of the US by road bike.
