Whistle B-Rush C4.2 - Ride to the top and quickly attack the most technical descents at maximum speed.
The B-Rush C4.2 is built for competitions but thanks to the sturdy suspensions, it's agile and fun even on trails near home. Benefit from a finely balanced system that delivers maximum performance for a sporty riding style.

New frontiers, new goals to be achieved, new opportunities. A carbon frame designed to maintain the rigidity that distinguishes this material, but designed to withstand high peak power, generated both by the rider and the drive unit. A frame designed to combine muscular and electrical performance in a seamless way.

Lighter and stiffer

The monocoque frame is made from a single mold, there are no joints between the pipes, such as gluing or bandages or welds (aluminum), where the efforts of the structure are concentrated. Advantage par excellence: weight. Processing in a single large mold allows the structure to be treated as if it were a single tube.The main value of carbon fiber is that it can be oriented so as to provide stiffness or flexibility in the critical points of the frame according to the design needs. This allows you to create frames that are very reactive but also capable of absorbing vibrations and at the same time saving material where it is not needed, thus reducing weight.
