Just replying to my own thread to start 🙃 When talking with Riv, they mentioned that bottom brackets for shipped framesets would be 110 - for a 45mm chainline.
Fast forward, I didn’t think to measure it myself. But another thread recently had me second guessing… Sure enough, measured, and voila, 113! So that answers a lot of my own questions on rough shifting! Next up, I’m trying my hand at a 47.5 Altus triple FD and expect it to be smooth as butter. And if not… well, I’ll certainly let ya know!
