I am a retro-grouch with tons of old bike stuff dating back to the 1970s. I have some good 27" wheelsets and other vintage components looking for a bike frame to build on. I see some good stuff on e-bay once in a while, but I'm always suspicious. Thrift shops and GW stores have left me cold - everything is very beat-up...can't devote the necessary rehab. time right now.

Short of going custom, is there anyone out there building or selling good, practical road frames (new or NOS) that will accommodate 27x1-1/4 rims/tires anymore? I'm thinking threaded forks/quill stems, etc. Would a Cyclocross frame have the extra clearance needed?
