It's Tim, Tom is my cousins name, and I've had my grandmother calling me Tom all night
I can try, but to be honest, I'll do most of it by checking against Bikepedia, and the numbers on the 4 DBs I have in my possession currently. Also helps if it's mostly original, the gearing often gives it away. I didn't even bother with my Sorrento, as I was so annoyed with myself, will check mine at the same time. Mine is too big for me (22"), and the crank arms don't match, but other than that is in better condition than yours. If anyone wants it, I'll sort pictures. It owes me £50 posted
I'm also out on the bike 3 hours from home tomorrow, so may not get a chance until Monday.
To be fair, they aren't that bad. The geometry is actually quite nice to ride, it's just they are built with the cheaper heavier tubes, and have crap componentry on them.
