Hi Hugh,

I checked my bikes, and here's what I found:

Ancora w/cambio Corsa & 4-speed fw - 110mm Benotto w/cambio Corsa & 4-speed fw - 110mm Olmo w/cambio Corsa & 4 speed fw - 110mm Learco Guerra w/Paris-Roubaix & 4-speed fw - 112mm Bianchi w/cambio Corsa & 4-speed fw - 114mm

Anyone know the spacing on the Campagnolo tool "M" (apparecchio per saldare nelle giuste posizioni i forcellini per cambio tipo corsa Parigi-Roubaix e cambio Gran Sport) for assembling the rear dropouts? Unless it was adjustable, that should reveal what Campagnolo considered "standard".
