The Wabi crankset is the Andel RSC1 that uses a 103mm BB. This is different from the Andel crankset model that is used by All City and is sold generically that uses a 110mm BB. You should buy the 103mm BB that Wabi sells.

Edit - Wabi recommends using the 107mm BB with their standard crankset, so I guess I’m not sure what to recommend. I can only say for sure that the BB on my Wabi Lightning with the Wabi crankset had a 103mm BB. Since I’ve not pulled the cranks on my Wabi Classic that I bought two years ago, I don’t know the length of its BB. The cranks on both of my Wabis are the Andel RSC1. I’d suggest contacting Wabi to be sure.
