Built Frame with Bottom Bracket Backwards - Is it ok to thread cups backwards?

If BB shell orientation goes wrong, you can always configure the bike as a singlespeed with the chain looped in a figure 8 between the cog and chainring. Pedal backwards to move forwards and the BB thread precession forces will again be in cosmic alignment.

Mobius bike...................I like it.
Buy Paragon shells.
No facing needed & the drive side had a ring machined into it.

I think I enjoy the discussions around screwing up more than anything around here

If you have never screwed up, you have never actually built anything.
