The mystery is that I bought this off eBay as a 'Romester' and even though it had bad decals on it, I've been unable to find anything else like it, hence the Spesh decals.
I know it's 7005 alloy and TBH, it weighs about the same as a motorbike. Groupset is Campag Mirage/Veloce, wheels Fulcrum Racing & with Bonny Race-X-Lite tyres, Stronglight 48/34 chainset, ITM Millenium bars, stem and forks and a nice Rolls San Marco saddle.
The clever part is that I actually managed to get a 9-speed Shimano cassette onto an 8-speed freehub with Campag spacers. Took some work but the reward is a nice 13-14-15-16-17-20-23-26-30 that gives a bottom gear of 31 inches - yay for the easy ride up hills!
