I didn't know Reynolds had stopped making 531 and am really surprised since they've been making 531 since something like 1938? So is 725 the new 'standard' Reynolds tubing? I bought a Nomad last year and my wife one this year, both in 531 obviously and plumped for 531 partly out of prejudice, (I have been riding various 531 bikes since 1976 and have always enjoyed the combination of strength and comfort), and partly because I had heard that 725 was thinner-walled and liable to be damaged when handled roughly (by airlines for example). This was the prime mover behind choosing Nomads over the xTc, for example. I have no regrets, the Nomads are fantastic bikes, but I am curious to know if 725 has been beefed up to avoid accidental damage? Will Thorn decide to rationalise a crowded 26" wheel model catalogue and drop either the xTc or the Nomad?
