Product description What it does Tool kit for routing and securing hydraulic brake hoses through bicycle frames. Designed to make internal hose installation easier, reduce friction while threading, and provide a rust-resistant connection point. Key benefits Faster, smoother routing: polymer-coated stainless steel inner cable lowers sliding resistance so the hose feeds through tight passages with less force and fewer snags. Secure, rust-proof connection: aluminium alloy body, magnet and stainless steel parts resist corrosion and provide durable performance. Versatile use: includes three adapters to fit different hose end shapes and routing tasks, reducing the need for improvised solutions. Compatibility and size Compatible with carbon, titanium and aluminium frames. Not suitable for steel frames. Requires frame access holes larger than 6 mm. Materials and performance High-quality aluminium alloy main body plus magnet and stainless steel components for longevity and corrosion resistance. Polymer-coated stainless steel inner cable for low friction and smooth threading. Three adapters included for different routing or hose-end configurations. Important installation note After final installation of the brake hose, cut 10 mm from the hose end to prevent oil leakage. Practical use scenarios Replacing a hydraulic brake hose on a carbon road bike with internal routing: use the low-friction inner cable and adapters to feed the hose through the frame cleanly. Building or upgrading a titanium gravel bike: route hoses through tight bends without damaging internal frame finishes. Servicing an aluminium commuter bike with internal routing: quickly run a new hose through the frame and secure it with the magnetic/aluminium connector while you finish the installation. What’s included Tool with aluminium alloy body, magnet and stainless steel components. Polymer-coated stainless steel inner cable. Three adapters to handle different hose-end shapes and routing tasks. Customer guidance Confirm your frame access holes are larger than 6 mm before ordering. Do not use on steel frames. Remember to trim 10 mm off the brake hose end after installation to prevent oil leakage.
