What Is the Shimano SM-BH59-JK-SS Disc Brake Hose For?

The Shimano SM-BH59-JK-SS is a 1700mm straight-cut hydraulic disc brake hose for Shimano MTB hydraulic disc brake systems using the SM-BH59 specification -- the standard BH59-spec hose used across Deore, SLX, XT, and XTR MTB disc brake systems. Replacing a damaged, compressed, or incorrectly routed hose is essential for maintaining optimal hydraulic brake performance: a compromised hose affects lever feel, modulation, and stopping power directly. The 1700mm length suits most MTB frame configurations including full-suspension bikes where rear brake hose routing is longer. The straight-cut JK-SS ends require olive and barb installation during hose fitting using the standard Shimano procedure.

Compatible with Shimano MTB hydraulic disc brake systems using SM-BH59 hose specification. Mineral oil system. Olives and barbs must be sourced separately. Installation requires a complete brake bleed after hose replacement.
