It’s not by accident that we’re starting to see a lot of riffs on the original bike rack design from 1up. As RockyMounts tells us, their patent expired about four years ago, which means there are a lot of companies trying to create their own racks that mimic the twin-upright, tire-only contact style.
A style that still has a lot of room for improvement over the original as shown by the first sample of the new GuideRail on display at Sea Otter.
On the surface, the RockyMounts GuideRail looks a lot like a 1up rack, and it functions in the same way – vertical uprights press against each tire, holding the bike in place on the tray without any frame contact. Those trays can hold bikes with tires up to 3″ wide, and with wheelbases up to 55″. Weight per bike is capped at 60lbs for the two-bike rack, or 45lbs each if you add the 1-bike add-on kit for a 3-bike maximum set up.
The details are where things start to get interesting. For starters, all the pivot points have brass bushings to prevent any aluminum-on-aluminum contact. That will keep the rack functioning smoothly over the long run, regardless of conditions.
Along those same lines, while most of the rack is made from metal, the ratcheting mechanism is actually made from plastic. While that sounds counterintuitive, RockyMounts found that the reinforced plastic was actually stronger and lasts longer while maintaining proper function of the ratchet system.
