|are 6 speed and 7 speed cassettes the same size? So I can go from a 6 speed to a 7 speed without much work on a friction shifter bike? I think the spacing is 126mm. Thanks for the info guys...|

|suntour, dura-ace and i think regina 7 speeds freewheels are the width of a regular 6 speed freewheel - others like sachs sram, sunrace etc etc are slightly wider.
in thinking that you have a campy 126.5mm width axle here is a pic and a link from sheldon that may help...
in my experience a 7 speed dura-ace freewheel was a good fit and the chain on the biggest (12 cog) cleared the stays as well. make sure before you buy though as they can be a little pricey but are the best freewheel in my opinion followed closely by suntour.

|The spacing of both is either 126mm or close enough to it that the 'upgraded' rear wheel will slip right into the drops slick as a whistle. I've never heard of anyone encountering problems doing it. I've done it several times myself.|
|Wait, another question...||tronracer|

|I have a super record wheelset with open pro rims. I can just swap out the cassette right?|
|Yep. Screw the old one off, screw the new one on. Go to||scottfree|
