My large chainring on the road bike is AB. Bought it simply because I cracked my shimano one and mid 2020, AB was the only company that could get me back up and running in a reasonable amount of time. I know people that swear by oval. Seems to make more sense on MTB than road.
I dont love my chaining, I dont hate my chainring….its like the internet…if youre not thinking about it, its working. I guess it looks cool?
Their customer service is questionable at best
