The Shimano SM-BH90-JK-SSR brake hose is compatible with Dura Ace, Ultegra, 105, Tiagra and GRX disc brakes. It has a straight connection on the lever side and on the caliper side and is characterised by a high stiffness value. Like all Shimano brake hoses, SM-BH90-JK-SSR can be shortened easily. One M9 and two different M8 bolts are supplied. If you use the silver M8 connecting bolt instead of the black M9, you get the brake hose SM-BH90-JK-SS.
