So no solutions I guess? No one bothers flipping an ENO hub?
Phil bottom bracket... adjust the crank inboard/outboard.
If you want to flip it, just get a crank/chainring set up that splits the difference. Either way you are off a few mm but the sun will rise.
Srlsy - I obsessed about this stuff a few years ago when I started riding the ENO. Eventually I forgot about it and just rode the hell out of it.
