Position on A Time Trial Bike

Time Trials is all about aerodynamics. Therefore, the most important thing is reducing the frontal area. The ideal is a flat back because the wind flow is much reduced. However, don’t force yourself to have a flat back if it is not comfortable. Lance Armstrong had a curved back and it never did him any harm (see:pic). Also, if you are not used to riding at such a low position, then gradually reduce the height.

• Even if you don’t do time trials, it may be worth thinking about your position on a road bike. Comfort is more important than on a time trial bike, but, maybe a few changes can decrease wind resistance with little negative effect.
• Note: there comes a point when lowering the tribars can start to decrease power because breathing is slightly restricted. It becomes a trade off between aerodynamics and power.
• In the picture above notice how much lower the tribars are compared to the saddle.
• The second most important thing is bringing in the arms. On a road bike they are about 42cm apart. But, using tribars you can bring the arms closer together and reduce the wind resistance.

Graeme Obree – The Best Time Trial Position?

Graeme Obree in the Superman position. It is called the superman position because his arms are stretched out. Notice how flat the back is and hence how aerodynamic position

The Tuck Position

In this photo, Graeme Obree is showing another very aerodynamic position because his arms are tucked in like a skier. Graeme Obree was one of the world’s greatest time triallist. He was world champion twice and broke the world hour record twice. He was also an innovator, creating these unique riding positions. These positions were later banned by the UCI. Graeme Obree Bikes
