A disc brake-specific aluminium wheel designed from the ground up to be one of the most cyclocross racing wheelset.

The results speak for themselves, they won a world championship and two european championships.

A new era of wheels

The Prototype Crater wheels is designed for allroad enthusiasts looking for the ultimate performance.

As such, the tire bed has been developed for use with 36mm tires and is capable of withstanding frequent tire installations and removals.


Main objective – overcome the most difficult terrain conditions.

The Crater rim is 25mm wide and 30mm deep. One of the great benefits of developing a rim for disc brake specific use is that the engineering team is no longer bound by the constraints caused by braking on the rim. The result is a rim that is substantially lighter and more compliant without sacrificing the strength or impact resistance of the rim.

Accelerate, corner and sprint faster with lighter, stiffer wheels

At Prototype , we love the sport of cyclocross and over the years, members of the cyclocross community have been some of our most loyal and vocal supporters.

As such, we wanted to develop a specific wheelset for the die-hard  racers of the world.

The highest rolling efficiency of any tubeless road wheel system

The rims come in a 24 hole count only to maintain an optimal degree of stiffness and strength required for the frequent accelerations and confort.
