If you’re planning to shorten your Shimano brake hoses, these fittings are just what you need. Each set includes one needle and one olive, which is enough for one brake. These fittings are designed to fit the Shimano BH90 high-power hydraulic brake hose, which is standard on most (2012-newer) Shimano MTB disc brakes. It’s important to note that these fittings are NOT compatible with any other hoses besides BH90, and proper hose shortening procedures can be found in Shimano’s official technical instructions.
