2 cents worth.
I have 2 of these.
The first one I built was intended to be something I could lock on the street in Central London (What was I thinking???). Ended up with:
An early 90s Master frame.
9 speed Dura Ace with Down Tube shifters (I wanted STIs but if they went pop I'd have trouble replacing them)
I like it a lot but it was a bit small to be honest and as much as I liked the lines of no STI, it was a bit of a faff.
So I gave it to my Dad to knock about on (knowing that it wouldn't turn a wheel. Meanwhile I got back to riding on a Time.
I struggled with the Time. Very light, stiff, and comfy for the most part but I never really enjoyed riding it.
So earlier this year I found a Master X Lite on ebay (bit bigger), put on DA7900.
I also sourced some other kit like a 3t Titanium stem
2 sets of Forma SL bars (44&46)
Flite Titanium seatpost
For wheels, I have a set of 303 tubs badged up as FIR (Not my preferred choice but they were practically free. I'll keep them until I can afford lightweights) running on Corsa CX SC.
and a set of 7400 dura ace laced radially with bladed spokes to Open 4cds. These are running on 27 section Open Pave CGs.
On order, I have PMPs on TB14s.
I am amazed at how light this has come in. Not much in it between this and my friend's Record equipped Canyon.
In any configuration, it rides beautifully. Everything operates in a reassuring manner that seems absent from carbon frames.
I do think its far too nice to have as a winterbike but I guess it depends on your climate. I've cleaned it up after a wet summer ride with some kitchen wipes. Not sure how this would work after a wet winter ride.......
