Advent 9 proper chainring
I have an advent 9 system built into a bike of mine. Currently it is out of commission but I’ll be fixing it up soon.
the advent 9 was advertised as a single chainring system but I installed it with a double crank set. The double is too high and I end up spending a lot of time in the lower 34t cog.
im thinking of doing it the “proper” way and installing like a single 38t instead.
so the issue I’m wondering about is chain angle. I believe that 9 speed chains are not designed for angled use. With a single chainring there will be more extreme angles. Extreme angles increase chain wear and decrease efficiency
rear cassette goes from 12t to 42 t.

It'd be a pretty cruel joke to design drivetrain components to be used with a chain that can't handle the rest of the drivetrain.
