Still looking for that "go anywhere, do anything" rack? Well, the Axiom Flip-Flop DLX seatpost bike rack fits the bill. It attaches to pretty much any sized bike- whether it has rack mounts or not, is easily removable when you're not using it, and can haul up to 15kg of gear.
Versatile, easy to use rack fits all frame and wheel sizes
I use this to carry a couple of panniers carrying no more than 20 - 30 lbs, and much less when I commute. It effectively carries panniers, and mounts to the seat post quite securely. The fatal flaw is that the rack itself slips backward along the horizontally-oriented post, and the quick-release mechanism that attaches the rack to the post cannot be tightened. A temporary fix involved electrical tape around the post. Alas, it was only temporary.
Was this a gift?:
Bottom Line No, I would not recommend this to a friend
