42cm Bontrager Race Lite Aero Handlebar. Basically new; I mounted brifters and clamped the stem, and realized a 40cm would be a better fit for me. This bar has never even seen tape. What sets this bar apart from other AL aero bars is that it has internal cable routing (not just indents on the outside of the bar). On my roadie (now with the 40cm bar), I wrap the hooks, but left the tops bare for better aero and a nice clean look.
List price is $89
