SPIEGLER BRAKE DISCS 
Brake discs are some of the most heavily stressed parts of a brake system.
They have to be extremely durable, not just under racing conditions. Touring bikes and heavy custom bikes also make considerable demands of the rotor. Equipping road bikes with top class rotors is anything but a luxury or excessive gadgetry. For example, the outer ring is subjected to the most stress. It must be able to absorb the heat generated by braking and give it off into the environment without damaging the material. It must be constructed such that tension and temperature fluctuations of up to 700°C can be absorbed without cracks, distortion or breaks occurring in the material.
SPIEGLER outer rings meet all of these requirements perfectly. Selected materials and top manufacturing quality guarantee precise fitting, perfect operation, extremely long service life and exclusive design.
