The CAT DH Prototype is among the first carbon downhill bikes in MTB history. Jürgen Sprich of the SCOTT International Racing Team became European Champion on this bike. It features a Swiss-made CAT carbon frame with integrated rear suspension. A few of the only-10 prototypes ever made came with a handlebar-activated suspension system.
