Galfer is launching its latest and most innovative Shark Disc® MTB brake disc! The optimal design for the best possible performance is achieved through laser cutting technology. One of the key unique features is the internal "Shark Teeth" (cooling fins) that give the disc its name: Shark Disc®. The interaction of the teeth with the numerous small holes in the disc helps to reduce heat generation, while the outer wave design and side openings ensure strong and consistent braking performance.
