M-System Mountain Brake Housing - 5.0mm x 40m

Shimano M-System Mountain Brake Housing in a 5.0mm x 40m bulk spool is OEM-style housing designed for Shimano cable-actuated MTB brake systems. It’s a practical choice for riders and home mechanics who want consistent lever feel after a housing refresh, and for shops building multiple bikes or keeping common service parts on hand.

• 5.0mm MTB brake housing size - Correct diameter for typical mountain bike cable-actuated brake routing and lever/frame stops
• 40-meter bulk “filebox” spool - Efficient for multiple builds, routine maintenance, and cutting clean, full-length runs as needed
• OEM bulk housing for Shimano cable brakes - Straightforward compatibility target for Shimano mechanical MTB brake setups and replacements
• Fresh housing performance - Replacing worn, contaminated, or kinked housing helps restore smoother cable movement and more predictable braking response
