These are the long version of the handle cables that ship with Rexy Wheels as standard These are the 550mm vs the standard 300mm, which allows you to back-loop the cable. This means you can run the cables underneath your unit (if mounted on tripod or Back Mount Bracket) and therefore bring the handle cables in from the sides instead of in front. 

These cables are ultra flexible , with braided sheathing and gold-plated connectors. This kit contains 2x long cables only, you must use your existing Back Caps to make them work.
