Shimano Disc Brake Hose SM-BH59-JK-SS Straight - 2000 mm

When Do You Need the Shimano SM-BH59-JK-SS Disc Brake Hose at 2000mm?

The SM-BH59-JK-SS at 2000mm is Shimano's longer-length hydraulic brake hose for builds where standard lengths come up short, including tandem bikes, e-bikes with longer cable routing paths, and frames with internal routing that requires extra hose to reach from lever to caliper without tension. The straight-cut ends and stainless steel olive fittings are pre-installed for a clean connection to compatible Shimano low-pressure hydraulic brake systems, including Alivio BR-M4050, Altus BR-M395, and road disc models BR-RS405 and BR-RS505. OEM fitment means no adapter hunting and no improvised connections.

The low-pressure design used by these systems puts less fatigue on hose walls and seals, extending service life between bleeds compared to DOT fluid high-pressure setups. Cutting to length requires a proper hose cutter and a fresh olive and barb fitting at the cut end, so order slightly longer than needed if you plan to trim. For replacement or new builds where factory hose lengths are insufficient, the 2000mm SM-BH59-JK-SS is the correct OEM-spec solution.
