Changing crankset and BB
I'm planning to replace my crankset and BB. The current BB width is measuring 110.65mm, and the crankset was an All City Track. Was planning to do the Wabi (Andel crankset) which I understand is the same thing. Wabi offers a 107mm BB, is that close enough to my old chain line that it won't create issues?

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.

Maybe I'm better off with this crankset since the recommended BB is 110mm, and I had a good chain line with a 110mm BB?

Yes, that’s a great crankset at a great price. I’ve got three of them, even raced on them, and they have worked great. 👍

The crank will determine what bottom bracket axle length you need. If you're replacing both the crank and bottom bracket, use the manufacturer's recommended axle length bottom bracket. If you're just replacing the bottom bracket, your replacement BB should match what you're using now, unless you have a compelling reason to make a chamge.

So I bought the Wabi Crankarms and a 107mm Tange BB per Wabi's recommendation. Oddly enough, it doesn't come with instructions, so I'm not sure how much to torque the BB or Crankarms (or chainring for that matter). Anyone have some insight into this? It's Saturday so I'm sure they're closed for the weekend.
