BB for Soma Rush?
Hey everyone, can't seem to figure out what size bottom bracket I need for a soma rush frame with miche cranks. I keep seeing people say miche needs a weird size or something. First time building my own bike so I don't know too much about this ****. If you guys know of a halfway decent bb that would work with this setup (that won't run me 1 million dollars) that would be awesome. Thanks a lot.

Under specs: "BB: 68mm English-threaded"
https://www.retro-gression.com/colle...bottom-bracket
Choose "English"
Seems like the logical choice but I could be wrong.

Some Miche Primato Pista cranks are ISO, some newer ones are JIS. If you have a JIS set, it will say so on the arms near the crank arm bolt.
This being said, you need a 68x107mm BB (either ISO or JIS, depending on which version you have).
