Bike Internal Cable Routing Tool Kit with Frame Foam Housing, Magnetic Guide for Brake/Shift/Hydraulic Lines (Steel Frames Not Compatible)

like the title says it works exactly like it should. strong magnets and makes life so much easier when running internal cables. I'm not rich enough for Bluetooth shifters and droppers so for now this makes life less stressful when setting up new bikes. worth the money for sure

The kit worked fine for hydraulic brake hose but is too big for the 4mm shifter housing holes in the frame.

Anyone who has ever tried to route an internal cable on their bike knows that it can be quite challenging and frustrating at times. The easiest way to route internal cables is to use the old existing cable to pull the new cable through but this is not always possible. This TORCHPILOT Bike Internal Cable Routing Tool Kit simplifies the process by the use of magnets and various adapters. There are three adapters included - one each for brake cables, shifter cables and hydraulic hoses. The polymer coated stainless steel cable ensures smooth sliding through your frame.The included 6mm OD foam sleeve can be used if you are having issues with frame wear and rattle from the internal cables. I don't have these issues so have not yet used the foam sleeve but I do appreciate having it on hand in case any issues arise. Can be used for internal or externally routed cables.Overall, anything that helps and simplifies internal cable routing is a winner in my books. Highly recommended.

I get the appeal, to prevent the cable from smacking around when internally routed. However, I found the foam housings a bit too thick, and sometimes it gets stuck on the inside of the frame.Other than that, the tools are simple and work well
