This is the worlds first cable guide to fit 4 cables and. This means that you can now mount the cables for your derailleurs, your rear brake, and your dropper post onto your frames cable guide mounts to give a clean looks to your bike and do away with those zip ties. This version accommodates 2 standard size gear cable outers, 2 standard size hydraulic hoses (brake hose and a Rock Shox Reverb hose). You can also fit a standard size cable brake cable into one of the hose slots. These are still undergoing testing so please send feedback as to what you thought of them and if any improvements can be made.
