Everybody sing! It's beginning to look a lot like syphilis Christmas… and that means it's time to put the old bikeapotamus up. If you're trying to cram more bikes into less space, Delta Cycle is here to help. Among their various bike racks is the Chagall Quick-Adjust Tension model. This two-bike model assembles quickly and adjusts easily to fit ceiling heights from 7.5 to 9.5 feet.
The Chagall looks nice enought to be used in a living space, but it's not just another pretty face. The four arms, two for each bike, swivel freely and adjust independently vertically to accomodate your bike's frame. There are two accessory hooks for helmets or whatever. All the hooks are rubberized so they grip without scratching.
All in all the Chagall is a sturdy and useful setup. The only minor quibble is that the two vertical supports are fairly close together, and if your bike needs to be supported in weird places (Gary Fisher full suspension mountain bikes, anyone?) you'll need to put the arms at a fairly wide angle. Like the man said, minor; with a little creativity it should do for just about any model.
