I am in the same position of needing an aerobar/base bar set up. While riding on Sunday morning, the right arm pad snapped right off and the thing is trashed. It is a wonder I did not fall right off the side of the bike. In any case, I am not that picky if the price is right.
I have a brand new Profile Design T2 wing base bar. Maybe some other stuff.
I have a set of Syntace C2 ultralights (390g.) I’ve only used them a few times. I have the computer mount post, and the aerolink as well. I can sell them all for like 80 bucks.
