I have a Truvativ XFire chain rings on my bike. Lately I noted my middle ring (32T) is not flat, and wavy in two spots. Is that normal for after two years of use?? I'm 5'4" tall male, 135lbs...not heavy.
I have on my other bike Shimano LX AND it is nicely flat ( after 20 years!)...
Is Truvativ that soft????
