Shimano Ultegra SM-RT800 brzdový kotouč Centerlock 160mm (BULK)

The Shimano Ultegra SM-RT800 is a high-performance brake disc that gives you maximum control on steep and long descents. Thanks to the innovative ICE-Tech FREEZA technology, the brake stays cool even under extreme stress and delivers consistently reliable braking performance. The sleek design is a perfect match for modern bikes and operates completely unobtrusively.

Thermal intelligence meets braking performance

The innovative sandwich construction of this brake disc consists of an aluminum core encased by two robust stainless steel layers. This combination ensures excellent heat dissipation and prevents thermal deformation. The integrated cooling fins further enhance heat transfer, minimizing brake noise.

Reliability you will feel

Thanks to ICE-Tech FREEZA technology, brake fade is significantly reduced. You get consistent braking performance on every descent. Brake pads last longer because they are exposed to less heat. The Center Lock system allows for easy and secure installation without complicated tools. Whether you use organic or metallic brake pads, the rotor works reliably with both.
