For sale $120.
Virtually new condition. Used only once for a short-trip to the bike shop. Purchased last year for $300.
It holds 2 bikes. Bikes are supported by the wheels, with just rubber straps to lock-down the frame to prevent swaying. Good for carbon-fibre bikes, where you don't like to clamp onto the tubing, and also for dual-suspension bikes, which may not have accessible areas on the frame to clamp onto.
I've bought a new car, and have decided to use roof-racks instead.
