|I'm thinking of putting 9 speed shimano wheel on an old Colnago Super Piu - circa 92/93, made for six or seven speed (maybe 130 mm?). Can I just pry open the rear triangle to make it fit or spread it permanently. If permanent, is there a special way to do it or special tools needed? When shops do this do they just yank it apart until it has the right gap? Don't want to hurt my frame.

|I'd try just wedging the wheel in there. nm||OldEdScott|

|I just read the Sheldon Brown article. Yeah, man - just take a piece of lumber to your precious old Colnago and start yankin'... If you wanna' play Torquemada to your Italian steel, maybe you oughtta' experiment on a thrift store Centurion first.|
|..well, steel is very compliant, should not be a problem. nm||Spunout|

|The absolutely correct way is to put it on a frame alignment table and adjust it until it's wide enough and then align dropouts. I've noticed that a lot of steel frames are a bit wider than 126 anyway so its not that big a deal to just stick the wheel in there (thats how my 1982 Guerciotti frame is and my wifes Colnago too) The worst thing you might do is if the dropouts are crooked it may affect the rear hub bearings, other than that it shouldn't be a problem.|

|I took a guy wire tensioner (the size you would use on a clothesline). They have eye bolts on each end and the internal threaded barrel in the middle. I put the eye bolts on the inside of the dropouts in that little triangle space. I turned the barrel to spread the frame. I figured it would apply even pressure to both sides so it would track nice. I over stretched by several mms and let off tension and measured. I stretched again until it was right.|
|That is a good idea. Thanks NM||dave woof|
