Shimano Deore SM-BH90-SS Hydraulic Disc Brake Hose

Shimano hydraulic brake hose — the fluid line between lever and caliper. Lengths vary with frame and routing; the hose needs to be cut to fit and bled after install. A service-item more than a consumer-upgrade; you replace hose when you change frames, re-route for a cleaner install, or after damage. Deore is Shimano's workhorse MTB group — proven, serviceable, commonly spec'd on mid-level trail and commuter builds. This is the Shimano Deore SM-BH90-SS Hydraulic Disc Brake Hose.
