I have front chain rings 22/32/42 and installed a rear cassette 11/32 using Deore LX RD. I can shift into 42/32, but chain is tight so chain tension is ok. When using smallest gear 22/32 RD does not run smoothly even though RD is adjusted correctly. When using next to lowest gear 22/28 RD runs smoothly. RD runs smoothly in all others gears.
Any recommendations how to solve this will be appreciated.
