I'm looking for a road frame/fork with a top tube of 53-54cm. Somehow yesterday while riding, I broke the non-replaceable rear derailleur hanger on my steel Colnago Technos, and I need a frame/fork to build up and ride to tide me over to the fall when I plan on buying a more permanent replacement (I'm thinking ti, like a Moots or Lynskey). I'm trying to stay under $600 as this is more of a temporary solution.

Shoot me a PM if you've got something that might fit the bill.
