SHIMANO Ultegra Brake Disc Center Lock RT-CL800 | 140mm IceTech FREEZA
When developing the Ultegra CL800 brake discs, Shimano engineers managed to prevent the discs from deforming due to heat. As a result, the CL800 discs offer more reliable, better controllable braking performance and are quieter than ever. Fortunately, the weight has remained at the low level of the previous version.
Also on board is Shimano's 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 around a further 50 °C thanks to their increased surface area. Due to the higher heat dissipation, smaller brake discs than usual can be installed. In addition, the service life of the brake pad is significantly extended.
As is typical for Shimano, the discs are suitable for Center-Lock mount , which enable quick and easy installation, offer a secure hold and ensure a clean and compact look.
