Your MKM Ultimate doesn't happen to be an 'Ultimate' perchance? and a silver one at that?
Yep, and I like 'proper' TT bikes as well. Trouble is that they're not very usable on a general basis. However, I do pedal mine in anger occasionally. Next for a re-furb is a 1990-ish lo-pro - but with a sensible 700c front wheel! I have a period rear disc and a blade spoked Assos front wheel all ready for it.
I would still like to find a really short w/b frame to refit. The type with the front wheel virtually touching the down tube and short rear end for 6oz silks only! Totally impractical but so interesting as a phase in British TT'ing history.
I take it you've probably see Time Trialling Forum and the 'Legends' thread? Lots of photos of top riders and their bikes there.
Today is the yesterday of tomorrow.
