Hey, This is the place to show others about a problem that you encountered and how a component solved it. I installed an 11-50 Box Nine group set on a bike, but then it couldn't hit first gear, the 50-tooth cog. The chain couldn't go that far sideways. This is a 42-t chainring from Eco Cycle. It brings in the chain line by 10mm and is narrow/wide to better hold the chain. The BCD is 110, just what I needed for that bike's motor. And I got single ringbolts for a clean look.
