Comfort, longlife bikes and reliable quality are at the forefront of the Cube mountain bike COMP Series. COMP Series models are particularly suited to keen sports leisure riders, who seek their challenge in cross-country mountain bike riding and so need a comfortable, light and reliable hardtail mountain bike. COMP Series frames are mainly manufactured from high-quality, thermal-treated Aluminium. This aluminium quality is very rigid and fatigue-proof and has very good tensile strength and very high corrosion resistance. Cross-ovalised oversized cross-sections and use of the new "Advanced Mechanical Forming" process can reduce material use significantly whilst retaining accustomed stability. Stressed occurring at the steering tube are thus absorbed and ensure a high degree of frame stability along the direction of impact. The oversized diameter of seat tube, bottom tube and chain stays on the other hand are responsible for very good lateral rigidity.
