Neil, I got quite a few cheapy FD's if you want to try one and see if it works, I can let you have one for nothing if there's one that fits...
Rich, Whilst I found loads of interesting pics that made me laff, can't find one anywhere of the Raleigh RTB, sorry, but I will keep looking through the Cycling Plus mags...
Thanks for the offer, I'll let you know.
I am keeping my fingers crossed that if I hit it with a big enough hammer... erm, if I engineer the solution correctly, I should be able to get it to work.
I know I can get a SRAM X9 mech to work on a 2 x 10 setup with a 28.6mm seat tube, as I have done two of these already. The question is whether I can get a SRAM Rival mech to reach all the way out to the big ring. Theoretically it should work, but as we all know, theory is one thing, practice is a different animal all together.
