I have a p7 which I originally bought with a7 speed stx rc groupset which is superb.
Definetley worth keeping , Still using some of groupset on different bikes.
Regards the forks, the F7 is a vastly superior fork to the RC-35. As pretty/cool as early Pace suspension forks are, I also think the colour matched F7 looks better too.
I'll have to get to a retrobike meet with it at some point. Be interesting if your pal did build it ginger. Was that back when they were still in the shed round the corner? He could well have given me the contact details of the bloke I got my first Clockwork off BITD.
Defo saving the Pace for another build so the F7's will be staying. Planning on giving her a clean up this week then I'll post up some better pics.
