I have an Easton EC70 carbon anatomic wing handlebar, 42cm width, 31.8mm clamp. It's barely used and has no residue since I only use non-adhesive bar tape. I'd rather have a bar with a classic (pro) bend and a deep drop (140mm or more). Aluminum is fine, and I don't even want any cash if your bar is of lower value. Let me know what you got.
If you don't want a bar, I also have a white and blue Toupe Team 130mm saddle, or a brand new Specialized carbon seatpost (take-off from an Allez Elite).
