Shimano SM-RT86-S 160mm Disc Brake Rotor 6 Bolt Road/gravel/mtb Ice tech. Selling due to buying a new bike, my XT brake discs 160mm. These in my opinion along with the XTR and one of the top braking systems on the market. I’ve used Xt brakes to compete in the mega avalanche race and they were amazing. This disc was 1.8mm new and is now 1.6mm ????????
