"I received my beautiful Absolute Black oval XX1 style chainring. I mounted it up, spun the cranks and thought to myself "this is going to be weird", but I jumped on the bike and it did not feel weird at all. In fact, it felt just the opposite. My pedal stroke felt more natural and the cranks felt easier to turn. What was great was that moving from a standard 30t, my low gear felt lower, and my high gear felt higher. It felt like my gear range expanded.
Super happy, can't wait to log more miles.
For those who worry about clutch mechanism in rear mech:
Oval ring does not affect the work of rear dérailleur cage at all. Such a ring can be used therefore in 1x9/10/11 combination as well as Singlespeed and fixie bikes!
