Hey Eric, Been loosely following along. Glad you were ok in the accident but sheesh, what a bummer it did so much damage. Id vote along with others for getting a hanger alignment tool, or figuring out how to make one for yourself. i bought a wolf tooth variety ( i prefer the way it references to the hub vs rim) not too long ago and dont regret the investment. I bought after knocking my appaloosa over on the drive side.
I will say i am curious too whether there might be something else going on to cause the skipping.. when my hanger was bent it was only noticeable that when in my biggest cassette ring the derailer would go into the wheel. may depend on what way its bended. I’m curious if the derailer may have any wiggle in the elongated hole. have you tried subbing in another derailer or chain to test the system? I encourage you to keep trying to solve on your own before reaching the final solution of frame repair or sending cross country, which would be time consuming and expensive. I can’t imagine what antonio or mark would do that you or someone more experienced on the east coast couldnt achieve. -stephen On Thursday, August 3, 2023 at 9:33:06 AM UTC-4 CJ wrote: > Can you elaborate on "the chain skips"?
