Most british built bikes were made with Renolds 531 or 530 tubing or Curtis used aircraft tubing . But what did the Yanks use 2 make theres ? Did they use renolds tubing ? I cannot c how, why would they ship our TI made tubing over the pond it wouldn't b cost effective surely ?

I thought the yank bikes were just made out of show chrome ;)
-
Some Quadangles are Reynolds 531 tubing ???

They did ship initially.
The 1979 rampar R11 & R11 XL were manufactured by Raleigh in the far east using British tubing for the American & Australian market.
Only initially though, later runs of bikes 3 year run were just chromoly instead of 531

Wasnt it 4130 chromolybdenum or crmo?
Reynolds cheaper 501 might have been thrown into the equation, but, as I remember when I worked for Raleigh, 501 was similar to cromo.
-
501 tubing was quite popular,have read a few articles on it :daumenhoch: but not sure how they converted it into Jeans for the convicts? ???

83-85 I think :-\
-
Very droll lol
-
Reynolds 531 is more or less the same as 4130 AFAIK
-
The 531 was made from manganese alloy.

Yeah your right, 531 is manganese-molybdenum and 4130 is chromium-molybdenum, the main difference is the chromium in 4130, however, they both contain manganese.
