Im building my new bike a Cannondale Supersix Evo 2016 frame which has BB30A (73mm wide)
I have a Sram Red 2012 group set with a BB30 crank set which was mounted on a Supersix evo 2015 (68mm wide BB30) and a Sworks Tarmac (61.5mm wide OSBB).
Im sure that the preload ring (non drive side) must be removed in order to get the 30mm spindle as long as as possible but ,,,,a wave washer and shims will be needed ????
so, will shims alone work, or is it advisable to have a wave washer, too?
The drive side spacers get installed as normal.
For the 2012 crankset is there a 5mm spacer too or just the preload ring? If just the preload ring then remove it and install with just a wavy washer. You may need 1 or 2 0.5mm micro shims to get wavy washer compression right but try without first.

just built up a 2016 hi-mod with the PF30a, and i did exactly as dudemanppl did -- remove the preload ring, put wavy washer on NDS, and away i went. no problems.
thanks, by the way, dudemanppl-- saved myself 75 grams over the stock hollowgram crank!
Hey, sorry to revisit but just found this threat. I'm doing a similar set-up with my new 2017 Supersix Evo hi mod frame and trying to figure out what crankset to go with the frame + eTap setup (and for some reason in France you can only buy Sram red complete kits with BB30 so now I have to get all the bits and pieces separately). Essentially, if I go for the Sram red crankset then I'll just need to buy a PF30a BB separately and it'll be good to go with the spacer swapped out?
(also, my old Synapse has a FSA-SLK crankset that I'd thought about putting on in the meantime but I'm guessing it won't fit as it's for a BB30)
Thanks in advance to all those more mechanically advanced than me!!

I am not a SRAM person, but a SRAM BB30 crankset that comes with a pre-load collar fitted can be made to fit BB30A. You just remove the pre-load collar and use a wave washer instead, adding other spacers as necessary.
Your old FSA crankset probably won't fit - the axle will probably not be long enough. FSA has since moved to BB386, which is really just an extra long 30mm.
