[MENTION=494396]sd5782[/MENTION] that makes sense.
When cleaning up the Colnago several years ago, I noticed a large gap between the smallest sprocket and the DO. This is a 6 speed but still 126 OAL.

I stuck a 7 in there and it worked out fine. Some frames can accommodate, others not. I have not heard of a 120 spacing work with a 6 speed with the exception of the Suntour, which I have experience.
