GuideRail Base With Hitch Bolt

What Our Gearhead® Experts Are Saying:

"I recommend the GuideRail Base With Hitch Bolt to anyone building out a serious transport setup for high end bikes. The 3 axis anti wobble system is the real standout here, the rack does not move, it does not rattle, and with 120 pounds of total capacity and a locking hitch pin included, it is a complete solution for riders who do not want to compromise on how their bikes travel."

Getting a race ready bike to the start line in perfect condition means the transport setup has to be just as dialed as the build itself. The RockyMounts GuideRail Base With Hitch Bolt is the complete replacement foundation for GuideRail systems, fitting both 1.25 inch and 2 inch hitch receivers and anchoring the rack with a premium 3 axis anti wobble system that removes every trace of movement, rattle, and uncertainty from the drive. Whether the route to the event is smooth pavement or a chewed up access road, the connection between rack and vehicle stays firm and controlled throughout.

The base supports up to 120 pounds across two trays and accommodates wheel diameters from 20 to 29 inches with tire widths up to 3 inches, covering everything from a featherlight XC race build to a more substantial gravel or enduro rig. Wheelbase compatibility spanning 36 to 55 inches means the system works across a wide range of frame geometries without compromise. Security is handled from the first install, with a locking hitch pin, lock pod, and 10mm square link security chain all included in the box.

For riders planning to grow their hauling capacity, the base is expandable to a third bike with an optional add on tray, making it a long term investment in a transport platform that scales with the quiver. When everything the season demands is loaded onto the rack, the GuideRail Base With Hitch Bolt ensures it all arrives exactly as it left.
