I used this Easton Attack TT aerobar for part of last seaon, but am switching back to ski bends. It's a super light and the internal cable routing gives a very clean look. In addition to the bars, you get: two sets of pads, two sets of spacers, extra screws (I think they're intended for use with the extra spacers), spacers for use with a 31.8mm stem (without these spacers the bars can be used with a 26 mm stem), the box, and the instructions. I will also include a pair of Profile Design arm rests and pads that fit on the Easton bars, which gives some additional adjustment potential. These bars are in great condition, with the only scratch being a mark in the clear coat that was there when I purchased the bars new (see the third picture) and that could probably be easily fixed with some clear nail polish. $275 shipped in the US.
