Used by professionals in the Tour De France, these bikes are also available to anyone who is looking for the ultimate in road-race performance. Every part of the bike is constructed from the lightest material that suits the function it is performing.
So, for example, fat tubes of thin walled aluminium are used to form the main triangle of the frame. These tubes are exceptionally light and stiff, which prevents any energy from being absorbed by the frame and allows it to go into accelerating the bike. However, fat tubes also create a harsh ride, so the fork and seat stays are made from carbon fibre because of its capacity to absorb shock. This provides comfort to the rider and no loss of performance to the bike.
Titanium saddle rails and derailleur parts, and carbon fibre brake levers are also incorporated to ensure that weight is reduced on the bike wherever possible. Nowhere is this more important than in the wheels – lighter wheels are easier to accelerate, and fast acceleration is key to successful road racing.
