I have come across a Claud Butler ( Holdsworth era) fully built up.
The bike is 531 throughout and is in pretty darn good shape.
The drive train is all Campy Super Record, including SR high-flange hubs, One of the chain rings is a Sugino however.
The onlyu off-note is the brake levers. They are old 105 aero's. I guess the owner wanted to run his brake cables under the tape.
This is a real nice looking bike - anyone have any thoughts on value??
