I bought a 34T 104mm Rocket middle chainring for my bike which has a 4 arm LX crankset. The chainring is about 2 weeks old. I suspect it was bent when I bought it since I have not crashed the bike or hit the chain ring on anything. The chain kept skipping when I was on the middle chainring and would autoshift to the small, despite the proper adjustment/allignment of the front deraiileur. When I looked down I saw the chain wobble badly on the middle chainring when I spun the crank. Now I'm wondering how to straighten it with the big chainring in the way. I've used a crescent wrench on other bent chainrings in the past with marginal success but that was always the big ring. Is there a better way? How to get around the big chainring blocking the middle one? Any advice?
Thank you in advance.
