Frame tubing Renolds 531 question
« on: August 06, 2012, 10:08 PM »
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  ;)
Sixteen thirty-two. What is that? A year?   No, it's your top score on Pole Position.

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.

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.
