Think carrying a bike on a rack sounds like a hassle' Try carrying a double sized bike. Tandems present their own particular logistical challenges when you're trying to transport them long distances. The RockyMounts Tandem Tailpipe Bike Rack makes life with a tandem a bit easier, however. Widely spaced dual straps support the bike after you pop it into your trailer hitch. The anti sway arms fold down when they're not in use, and the entire mechanism pivots away from the rear of the car when you need to get into the trunk. Attaches easily to both 2 and 1. 25 hitches.
