|The bike is set up with shimano 600 7 speed.
the right shifter went south.
Can the rear triangle be opened up a bit or is this too dangerous ?

|I've done it on several occasions all you need is 2x4, caliper and a bit of patience.
here's link from Sheldon guru Brown on how to http://www.sheldonbrown.com/frame-spacing.html
if you don't feel like DIY LBS should have spacing tool good luck.

|Why don't you check the spacing before you start screwing around? My colnago of that vintage is 130, as I would think all would be. If it should happen to be 126 there is usually no problem spreading steel,but a framebuilder told me he would not do it on frames with chrome stays due to the possibiity of the chrome cracking,as the stays have to be spread way past 130 in order to take the set.Other option is just stick in the wider hub and ride it.|

|very good posts above. The sheldon brown article is helpful. The spreading is not that hard. It's only 4 mm; not that much
|2mm on each side no problem!nm||the bull|

|My bike shop put a 9-speed Ultegra group on my 1985 Bianchi steel frame. They had to spread the chain stays a little, but it was no problem.|

|just try wedging the wheel in there before I went the 2x4 route. Most times, that'll do the trick. 4 mm ain't much.|
