I have the Chorus 2012 11-s rear and have access to some SR jockey wheels.

It appears to be a straight swap, but thought I'd ask you guys as i did notice the part number of the bolts holding the wheels is different between Chorus and SR, although they look identical.

Anyone either done this, or can attest that it's a swap, or that I need the SR bolts (maybe they're just Ti...?) etc. etc?

Not too sure, but I don't think so. Well worth the swap, i did it and there is a real difference. Ask any LBS that does Campy.

Super record pulley bolts are aluminum, chorus are probably steel. That would account for the part# difference. Most likely a direct swap, i have no chorus in front of me.

Straight swap, no problem. Chorus bolts are hollow steel btw.

Brilliant guys, thank you. Excellent forum!
