Can anybody help me identify this bike? It's a Claud Butler with Reynolds 531 steel - that's all I know. enter image description here

    It would be easier if you took some close-ups of various features: the Reynolds 531 sticker (it will show if the frame tubes are plain gauge or butted), the dropouts, the lugs, the serial number, and so forth. <a href="homepage.ntlworld.com/nkilgariff/… a reference which may be of interest</a>.

  • Here's a working link to the reference in the previous comment.

  • It's a fairly standard road bike from the mid 80s. Based on the Wikipedia article for Claud Butler, it could have been manufactured by Holdsworth or Falcon. Aug 11, 2015 at 2:34

    The seat tube looks a bit odd. Does it extend all the way to the top there, or is that a seat post? Aug 11, 2015 at 11:36

This is a standard English manufactured sport bike probably from the mid-60's.

It used freewheel type hubs and from what I can see you appear to have modified the rear wheel with a seven speed freewheel. The original rear triangle spacing was probably 125 mm and the seven speed uses a 127 mm spacing. Usually someone would re-space the rear triangle and put a spacer on the right side of the axle and normally they would not re-center the rim. This would cause the wheel to be slightly off-center in the stays. It usually had no deleterious effect.12speed

    Where do you get "mid-60's"? The downtube shifters and cotterless crank are clearly indicative of a couple of decades later. Oct 11, 2015 at 1:11
  • Where were shifters before they were on the down tube? I'm pretty sure my road bike in the '60s had down tube shifters and my dad's Schwann Varsity was very modern with its stem shifters. From what I've read Stronglight invented cotterless cranks in the '30s.

    Single water bottle braze-one became common in the early eighties. Double ones (like this bike) in the mid eighties. Of course, they could have been added later.
