Galfer Shark MTB Centerlock Brake Rotor Pump the Brakes When your brakes start fading mid-descent, it is never a caliper problem - it is a rotor problem. The Shark addresses that issue with its signature internal fins: a dense pattern of small holes that pulls heat out of the rotor, dropping operating temperatures by up to 30% compared to standard designs. That cooler-running temperature is what keeps your lever feel consistent from the top of the run to the bottom, even on long alpine descents or repeated enduro stages. The one-piece construction adds stiffness and strength without a weight penalty, and the outer wave profile combined with lateral openings keeps pad contact consistent across the full braking surface. Every rotor is laser-cut - never stamped - from virgin high-carbon 420 stainless steel, then ground for perfect flatness and heat treated for the specific application. This is not a cross-shopping rotor. It is a purpose-built heat management system that happens to mount to your wheel. Shark fin cooling system, internal fins and small holes reduce operating temperature by up to 30%, keeping braking feel consistent on long, repeated descents High-quality carbon, stainless steel construction, laser-cut from a proprietary virgin steel blend for a higher friction coefficient, better memory, and warp resistance under heat Single-piece constructionincreases structural rigidity and eliminates the flex points common in two-piece spider/ring rotors Extended pad life, with heat-dissipating design translates directly to pad longevity, with up to 25-40% more service life over standard rotors Centerlock interfacefor fast, secure hub fitment compatible with Shimano-standard centerlock hubs | Galfer | Shark Mtb Centerlock Brake Rotor 160X1. 8Mm, Centerlock
