The estimation of aerodynamic drag in cycling through road tests has the advantage of considering actual cycling conditions. The main drawback is that its accuracy depends on factors of the testing scenario as the wind speed

The basic Whipple-Carvallo bicycle model for the study of stability takes into account only geometric and mass properties. Analytical bicycle models of increasing complexity are now available, they consider frame compliance, tire properties, and ride

In uphill time-trial cycling races, riders have to travel along routes characterized by high-gradient variations in the shortest time possible. Due to this gradient variation, the appropriate selection among time-trial bicycles and traditional road b

There is a tradeoff between power delivery and aerodynamic drag force when cyclists ride at different altitudes. The result is particular to the characteristics of the bicycle as well as the aerobic fitness of the cyclist. This work proposes a method

Aerodynamic drag is the main opposing force that a cyclist has to overcome when cycling on level ground at moderate-to-high speeds. Therefore, the aerodynamic study of the bike-cyclist set has been identified as a key factor for the analysis and impr

During the individual time-trial competitions in cycling, the cyclist’s skills are essential, but it is also important the race strategy. The race strategy includes the manner in which the cyclist competes and the selection and set-up of the cyclin

The uphill time-trial is a cycling race in which there is at least one mountain pass or a combination of lowand high gradient sections. Usually, climbing cyclists achieve good results in uphill time-trials; however,in addition to the cyclist’s abil
