When it comes to storing bicycles vertically, a wall-mounted hook that grabs the front wheel rim is what's usually used (although there are exceptions). It's effective but perhaps not always that attractive, plus it presents a head-banging hazard. The Clug offers a lower-profile, more interior designer-friendly alternative.
Created by Vancouver-based Hurdler Studios, the Clug is simply a flexible C-shaped bracket.
Its outer plastic "clipper" section is first screwed into the wall, using a template incorporated into its cardboard packaging to establish where the holes should be drilled. Adhesive picture-mounting strips will reportedly also work, if you don't want to put holes in your wall.
The soft elastomer "gripper" section is then placed inside the clipper. While the clipper provides the tension to hold onto the bike's front tire, the gripper provides the grip (appropriately enough) while also protecting the rim from scratches.
The designers are currently raising production funds for the Clug, on Kickstarter. A pledge of CAD$9 (about US$8.25) will get you one, when and if they're ready to go. The current version is designed to fit road bike tires, although a bigger model for mountain bike tires is in the works.
