With its innovative Shark Disc, Galfer presents the most advanced MTB brake disc on the market. The innovative production process, which uses a laser cutter, achieves an optimised design for superior performance. A key feature is the internal Shark Fins (cooling fins) that give the disc its name: Shark Disc. The interaction of the fins with the numerous small holes in the disc reduces heat build-up, while the external wave design and side openings ensure strong and consistent braking performance.
