Add-On Spine - MonoRail

What Our Gearhead® Experts Are Saying:

"I added this to my existing MonoRail setup when the group started showing up with three bikes and it integrated so cleanly it felt like it was always part of the rack. The front wheel only contact keeps my carbon frames completely untouched, and the whole expansion took about ten minutes to install without any special tools."

The group got bigger and the rack needed to keep up. The RockyMounts Add-On Spine for MonoRail is exactly the kind of solution that makes that conversation easy, slotting directly into an existing 2in MonoRail or MonoRail Solo setup and expanding carrying capacity without replacing any hardware already doing its job. Two bikes become three on the MonoRail and one becomes two on the Solo, all without touching a frame or starting over from scratch.

Bikes are secured by the front wheel with zero frame contact, keeping paint, carbon, and finish protected through every mile of highway and every rough access road that leads somewhere worth riding. The system handles wheelbases from 36 to 50 inches and tire widths up to 5.0 inches, covering everything from road bikes to fat bikes in the same tray without additional adapters or adjustments. Buy the rack once, expand it when the time comes, and never leave a bike behind because the setup could not keep up.
