A quote of another forum I think answers your question :
Quote:
..SUP is a process where Mavic welded the entire seam of the rim instead of just a pin weld. The seam is than machined smooth...It's supposed to create a better braking surface and stronger rim...

:wink:

Re the cranks, if its hollowtech it will be fine.

SUP does indeed mean the join in the rim has been fully welded and then machined.

I'm pretty sure the D521s will both be SUP welded, I don't remember them making one that was only pinned. So it's probably just a difference in labelling.
