Rock Machine has a super strong weapon for all cross-country & marathon cravers. Carbon hardtails in the Peak category. Excellent energy transfer, durability, manoeuvrability and superior riding comfort have made our Explosion carbon models popular with hundreds of enthusiastic users across Europe. From 2016 we equipped our carbon bikes with interchangeable MAD droupouts that ensure compatibility with two most widely used standards of the rear wheel axle - classic quick-release or thru axle 12x142mm. Depending on your riding style you can choose whether you want a model with 29“ or 27.5“ wheels.
