neeb -- I agree with you re. oversized bbs. My canyon slx has standard outboard bb and seemed stiff enough for griepel. I had a TCR advanced with bb86 and the campagnolo crank creaked away. also bb30 with exogram is far lighter even than super record with Ti axle.
I think it's just luck whether the tolerances of the particular BB30 frame work well with the Campagnolo press fit cups or not, I guess I've been fortunate.
Are you sure about the weight though? I thought both cranksets were about 585g? The Campagnolo cups are about 30g. Does the exogram weight include the bearings?
My exogram is 523g (without bearings). I have the bearings but haven't weighed them ... they aren't all that heavy though.
UT Ti is 585g plus 29g for the cups.
In reality if I was going Campagnolo I would use the existing Super Record crankset I have, which is non-TI version, and therefore another 50g to add to the above.
The SRAM crank is WW alright.
