I want to build a road bike with a 1X 42t drivetrain. The frame has a BSA 68mm threaded mount.
I figured the best would be going for a 110bcd 5 arm crank for max conpatibillity. (right?)
This shit is confusing as fuck.
What crank would I use which centers the single cainring line (where there would usually be two)?
Or can I use a normal 2X road crank and use spacers or adapters or something to center a single "small" ring?
