Time trial bicycles are a subset of road bicycles that are designed for time trial events. Recumbents were excluded from the UCI definition of a bicycle on 1 April 1934. Racing bicycles are generally legal for use on public roads and are widely used for non-racing fitness and utility riding.ĭistinction between road bicycles and others īicycles for racing on velodromes are track bicycles bicycles for racing off-road are mountain bicycles, cyclo-cross bicycles, gravel bicycles or cycle speedway bicycles bicycles that race according to the rules of the International Human Powered Vehicle Association include faired recumbent bicycles which, on flat ground, are the fastest bicycles in the world. It is common for professional road cycling teams to use prototype bicycles and equipment before they become commercially available. However, racing bicycles must retain the ability to maneuver safely within a tightly-packed peloton, and be sufficiently comfortable to ride for races of six hours or more.īicycles and most wheels ridden in professional competition must be type-approved by the UCI, and made available for commercial sale. The derailleur gear ratios are closely spaced so that the rider can pedal at their optimum cadence. The front and back wheels are close together so the bicycle has quick handling, which is preferred by experienced racing cyclists. The drop handlebars are positioned lower than the saddle to put the rider in a more aerodynamic posture. Racing bicycles sacrifice comfort for speed compared to non-racing bicycles. They are designed to minimise aerodynamic drag, rolling resistance, and weight, and balance the desire for stiffness for pedaling effiency with the need for some flexibility for comfort. Racing bicycles are designed for maximum performance while remaining legal under the UCI rules.
