That's a lovely build - did you have to cold-set the frame to get the 10-speed hub into the dropouts? Or is it just a squeeze? Interested to hear how you got on as I have a frame and forks from 1980 I'm considering a modern groupset on, though I might stick to '90s kit as opposed to 10-speed.
Thank you! The rear dropouts measured 127mm so I just squeezed the rear wheel in without much bother at all
I took the bike out to the club '10' last night, an extremely hilly course and I was surrounded by some very expensive carbon fibre TT machines, didn't stop me & the Gazelle passing 4 of them though!!!
if you want to fit Campag 8/9/10 speed into a 126 ish rear end, replace the thick cone nut on the opposite side to the cassette and fit a slim nut say off a scrap MTB wheel with a Shimano hub and the re-dish the wheel !! takes 2.5 mm off the width..
