Frame
No one seems to know, it as Ritchey Cowled drop outs, Reynolds 653/631/525 tube mix, reinforced head tube, Tear drop down tube and a lot of forming in the rear triangle. Bob Jackson did the Stoving and they reckond it was a very high quality hand built. The steel does not rust, I bare metal stripped it and blasted it and it stayed bright in my shed for months, unlike Tange/Columbus etc which rusts like hell. It's also very light at four pounds .Reminds me of the old Vitus and motobecane road frames with the narrow formed down tube.
