Im not sure where you're coming from with this. I wasn't rejecting your analysis, just asking for clarification so I could better understand it. In your earlier response, you said that a twisted derailleur could cause the bike to shift differently in the small vs. large chain ring. I never questioned that. If you carefully read my response, I said that it was my assumption that a bent derailleur hanger (not twisted derailleur) would cause it to shift the same in both chain rings. If you meant your analysis applied to a bent hanger as well, you should have said so. Don't worry, I won't dare question your supreme knowledge again on this forum. This is not the first time you've gone after other posters with the "don't ask for advice if you're going to dismiss it" line. I don't give a crap how long you've been in the business--it doesn't give you the right to speak to people as if they were a child.
