" The Shimano 600 AX groupset was the second line of shimano's Aerodynamic set of groups comprised if the Dura-Ace AX, 600 AX, and Adamas AX groups. Every part of the AX groups were designed to be as aerodynamic as possible, as evident by the brakes, seatposts and almost every other part in the group. The AX groups also used shimano's 1" diameter axle Dyna-Drive pedal system.."

"Dyna Drive – a pedal system with no pedal axle and with the bearings located in the part of the pedal which screws into the crank. This required an oversized hole in the crank 25mm (1" diameter) to accept the Dyna Drive pedals. The theory behind this was to allow the foot to be lower than the pedal axle for better biomechanics. This system was relatively short lived, one reason being that the pedal bearings wore out quickly. However, they were used by Alexi Grewal (USA) in his gold medal winning ride in the 1984 Olympic cycling road race in Los Angeles."
