"The GuideRail steps away from the traditional carrying style of platform hitch racks; By utilizing dual load arms, the rack completely eliminates frame or fork contact, it allows for asymmetric bike loading to avoid handlebar interference, and it creates a simple aesthetic that virtually blends in with most vehicles. The GuideRail reduces plastic parts to a minimum and maintains the same capacity and reliability of the MonoRail Family. Carrying bikes up to 60lbs per tray, tires up to 3 wide, and wheelbases up to 55 the GuideRail can handle just about anything including most E-bikes. Included is a 10mm square link chain to secure your bikes without stress. If you want to fit both 1.25"" & 2"" Hitches, purchase the 1.25"" model and the GuideRail 1.25"" to 2"" Adapter Sleeve"
