I installed a bash ring on the RFX crankset. I have not adjusted the front derailleur position on the seat tube at all. Currently the derailleur is set a little high so that the chain grinds on the bottom of the chain cage when the bike's in the work stand but is totally quiet when you are on the bike and the suspension compresses a bit. With the big chain ring gone, the FD looks a little odd with the big gap exposed between the cage in the middle ring position and the top of the bash ring. I'm inclined to leave it where it is so the chainstay yoke does not hit the chain cage on full compression. It shifts perfectly now - what have the other Homers done?
