Colnago's carbon-fibre Rock mountain bicycle has been setting pace on the 2011 World Cup scene. The star of the Colnago Arreghini team is Italian champion Eva Lechner, who was pressing for overall victory in the World Cup on Colnago's best-ever composite cross-country racing machine.

• Beta carbon front triangle is moulded in one piece for lightness, strength and stiffness.
• Advanced composites keep the Rock's weight down and ensures it can deal with frequent highimpact hits guaranteed in off road racing.
• Alloy drop-outs for durability
• Responsive and sure handling in extreme conditions.
