Not exactly C&V but I picked up a 9-speed Ultegra group (minus the brakes) for 75$CDN. It is used but in good shape and it turned out that the rear derailleur is a Dura Ace model that the
guy bought NOS on eBay 5 months ago!

I already have a spare set of Ultegra/Mavic CXP30 wheels so this group will probably find it's way onto my Battaglin.
