I recently did a 1x10 conversion on my mountain bike. I replaced almost everything on my drive train except for my crankset. The single chainring (104 BCD, 34T) fits onto my drive-side crank arm in the position where the large chainring used to fit (used to be 3-speed in the front). This causes some severe cross-chaining (if it's even called that on a 1x) when my chain is on the biggest cassette ring.
How do I move my chainring closer to the bike frame and therefore more to the center of the cassette? Can I buy spacers? Do I need to move my drive-side crank arm itself? Do I need to replace the crankset entirely?
