This Carbon Tech XBar measures 30" long using 1-1/4" diameter carbon fiber 1/8" thick wall tubing for strength. It features a unique rope ratchet system making it the easiest cross bar to use on the market. The rope is made of 1/4" no stretch synthetic material that is as strong as cable with an 8600 lb. breaking strength. This XBar is easy to use and very light weight. There are no chains, which means you'll have a level pushing surface every time.
