I sell a pair of aerobars Deda Elementi Parabolica Due Alloy Clip-On.
I bought them 4 months ago in order to struggle against the Patagonian headwinds and they've worked great. I'll be winning the battle very soon, so maybe they can be useful to someone else cycling on these latitudes.
I bought them for 90 USD and sell them for 45.
For the next 2 weeks I'll be hanging around Ushuaia / Punta Arenas / Santiago.
