Hey everyone! Some question about chainline that I’m struggling to make sense of. I currently have a 2015 Giant Reign 2 with the stock 2x10 drivetrain with stock Deore 104 BCD cranks. I recently got a 1x12 Eagle upgrade kit so I’m planning on switching everything out to 1x12 and want to keep my stock Deore cranks as I don't have the cash to upgrade those. I know I need to get a narrow-wide chainring, and was thinking about getting the stock SRAM Eagle chainring with 6mm offset. Do I need the 6mm offset? How do I make sure I get the right 49mm chainline, would a different chainring be better or do I need spacers? Any help or advice would be greatly appreciated as I have no Idea what to get and worry that if I take it to a bike shop they’ll just put everything on and not worry about chainline at all. Thanks!
