Colnago introduces the new Rock mountain bike for 2010, and it looks as if this hardtail is built to perform. Its structure is a full carbon monocoque frame with aluminum drop outs. The rear triangle of the Colnago Rock 2010 Mountain Bike has been specifically designed for a stable ride while being super responsive to acceleration. A square chain stay is used as well. The Colnago Rock 2010 Mountain Bike should do well for its 2010 debut.
