Good morning,
I'd be happy to donate a couple of rolls.

I was looking at a SPA titanium frame a while back and ran into the Elan and there were a couple of things that would have been important to me but maybe not to others.
There is a carbon fibre or steel fork option, fine, but the steel forks appear to be unbranded cr-mo, presumably non heat treated 4130 as nothing is specified and they weigh around 1.18kg. Nothing wrong with this but a long way from what my 753 forks, the tubing 725 is advertised as replacing, weigh, although they don't have disc mountings.
Stays material is again not specified, which doesn't mean that they are not 725 though. Back in the days when Reynolds "only" sold 501, 531 and 753 they were very keen for the customer to know which tubes were made from their tubing. They has stickers that said
frame tubes or
tubes forks and stays, along with a forks sticker and they have/had stickers that said
725 butted frame set and
725 butted frame tubes.
Raleigh and Dawes and probably many others used to make frames with the main tubes (top, seat, down and head) from 501/531 and then use carbon steel or unbranded cr-mo for the forks and stays depending upon the price. This allowed the marketing friendly 531 sticker to be applied to lower priced frames.
I know that I would be disappointed to have paid the premium for a Reynolds 725 frame only to find that the forks and stays were other materials.
Bye
Ian
