Leave a comment and tell us, so that we can update the list, bridge the gap, and keep it the most comprehensive cycling dictionary on the web.
aerobic: exercise at an intensity that allows the body’s need for oxygen to be continually met. This intensity can be sustained for long periods.
aerodynamic: a design of cycling equipment or a riding position that reduces wind resistance; aero for short.
anaerobic: exercise above the intensity at which the body’s need for oxygen can be met. This intensity can be sustained only briefly.
apex: the sharpest part of a turn where the transition from entering to exiting takes place.
attack: an aggressive, high-speed jump away from other riders.
audax: sometimes uses as a synonym for randonneur. More formally, audax cycling
is when a group rides a randonnee in unison at a steady pace of about 22 kph.
