Thanks for all this.. I thought myself campy sounded soft and rubbish, campag it is when abreviating from now on..
I will go for 6 speed as the (sheffield) Wilson frame is being cold set at my local shop at the moment to fit 126mm. It was 120mm. Basically I have had it stripped and some mig welding done on it (a long fine crack) and begrudgingly made the desition to cold set before paint.
I couldn't afford the time or money to find a nice 120mm hub that would almost certainly have involved getting the Mavicg 40's I had my heart set on built onto it. The hub i have is sweet! Got my dream rims and all affordable (just) plus the future is open to 126mm set ups now.
I may try build the bike up with the 7speed on but first.. Since posting this i learned the shimano 600 arabesque rear derailleur I have has a center to center range of 70mm so will get my gauge out on the block when its back from the shop.
The frame if you're interested is a 50th anniversary model hand built by the old guy in 98 I guess, it was red metalic and is technicly too small but I like that 56" and I'm 6'. It came to me in a mess with nothing but a saddle stem, rear mech and a sugino crank set worth keeping on it. Rust, a crack but no dents.
Final finish will be a translucent deep candy red (toffee apple)with a silver sparkle under it. I may leave of the main decals to show off the paint but will get the wilson name on the front and can even get the old 50th anniversary sticker from wilson too.
I am planning to use the bike for short hilly 10mile sprints on evenings (when little one is asleep) and the odd long haul in the summer. Also want gear ratios for down hill sprints with clocking high speeds in mind. Can't wait to get this on the road and some pics posted!
Thanks again, will post the outcome.. Alex
