I'm in the process of upgrading to wider bars so I've got a couple extras if anyone is looking.
Bontrager carbon bars - 640mm wide, 1" rise, 31.8 clamp, used for one season $35
Specialized riser bars - 640mm wide, 1" rise, 31.8 clamp, black, only used on two rides $15
Azonic riser bars - 28" wide, 1" rise, 25.4 clamp, white, never used $15
