I just bought a Surly Conundrum muni frame and Large Marge rim (24"). I’d like to get a hub and cranks for it.
Here’s the compatibility info:
- Bearing compatibility: 42mm O.D. bearings I don't feel like using shims so 42mm it is.
- Hub bearing spacing: 102-104.5mm, measured outside to outside
The cranks should be moments and 150mm in length
If you have anything else I may need… fire away 
I’m a newbie so I’m not in a hurry…
