The Hillbrick Birthday Frame and Forks is a project I'm working on to build this bike up as evrything that dates as close to 1969.
The frame is a Columbus Record tube set that has wall thickness's down to 0.5mm. The lugs have modified cutouts and use the older style Campagnolo long slot dropouts.
The next stage will be to add a Campagnolo Nouvo Record groupset to this build.
Stay tuned.
