What are the advantages of megaphone operators

Individual time trial - Indian termination policy

Working Anaerobic Threshold> Beginners are often criticized for trying to get a J-Profile, which means that they often work too hard in the beginning, compensate for this by reducing their efforts in the middle, and then notice towards the end that they didn't put enough effort into training during the race. As a result, the time trial is often seen as the toughest part of a large competition for young cyclists.

Time trial equipment

Special aerodynamic

Flat megaphone handlebars and regular drop handles were used before them until the late 1980s. In the late 1980s, triathletes developed so-called tri-bars, which allowed for a much better aerodynamic position. They were first brought to the public at the 1989 Tour de France when Greg LeMond overcame a 50-second deficit in the final day's time trial and won the Tour by 8 seconds by Frenchman Laurent Fignon. Fignon used conventional handlebars, Lemond the new triathlon style. The concept has hardly changed since then, only Scotsman Graeme Obree has tried to improve the idea. His arms under his torso were revolutionary and helped him and others break world records and win world championships. The UCI banned it in 1994, but he came back in the 'Superman' position, an evolution of the traditional tri-position but with his arms fully outstretched in front. This has also been banned, and there are now strict rules for the dimensions of the handlebars, which can make life difficult for taller riders who are outside of the defined parameters and have to adjust their positions to the rules.

The equipment used is very specialized, and component manufacturers can spend significant time and money on wind tunnel testing to ensure their product is faster than the competition. Deep or full disc wheels are often used to reduce turbulence around the spokes. However, these can impair handling in windy conditions. In the UK, for safety reasons, the front wheel must be at least 45% open when viewed from the side. UCI events still allow disc wheels to be used for the front, but it is very unusual. Many components have been modified for aerodynamic efficiency and manufacturers are now developing more integrated systems, e.g. B. in the fork or the frame built-in brakes so as not to disturb the air flow.

Clothing also differs in the time trial. One-piece skinsuits that don't flap in the wind are common. Tight Lycra overshoes improve airflow via buckles and straps. Long pointed helmets direct the air over the rider's back (the position of the helmet over the rider's back is crucial, it has to be as close to the body as possible, too high and the air only flows under the helmet. This is often difficult to do reach when the rider moves his head due to the suffering he suffered during a tough race).
