I'm designing a Fat bike around an ISIS BB and Middleburn cranks, measuring everything to make sure it all fits, and I cannot get the assembly info from FSA. Their instructions PDF locks up my computer, so:

Does anybody know if the Platinum Pro BBs require a 2.5mm spacer behind the drive-side flange? I assume they accommodate E-type front derailleurs, but wanted to confirm that they use the spacer.

I appreciate any and all help!
