Ok... Sooo my bike has a Cinelli 1E stem and a Cinelli 64-42 drop bar combo. Works perfectly... Bolts in the stem are rusty so I was going to swap it for an XA stem
The XA stem is 26.0mm and that appears to be what the drop bar measures out to be... But I can't get the friggin bar into the stem... What am I doing wrong here??
Heres some pics:
