Brake Disc Shimano Ultegra RT-CL800 Center Lock 140mm

When developing the Ultegra CL800 brake discs, Shimano engineers managed to prevent heat-related deformation of the discs. As a result, the CL800 discs offer more reliable, better controllable braking performance and are quieter than ever before. Fortunately, the weight has remained at the low level of the previous version.
Also on board is Shimanos Ice-Tech cooling technology, which ensures excellent heat dissipation and constant braking performance even on long, steep descents. The brake discs are characterized by a three-layer sandwich construction. Their stainless steel flanks with an aluminum core offer significantly improved heat dissipation. This allows the temperature to be reduced by around 100 °C. In addition, the FREEZA aluminum cooling fins reduce the system temperature by approximately another 50 °C due to their increased surface area. Due to the higher heat dissipation, smaller brake discs can be installed than usual. In addition, the service life of the brake pad is significantly extended.
As is typical for Shimano, the discs are suitable for center lock mounts, which enable quick and easy installation, provide a secure hold and ensure a clean and compact look.
