Sorry - i should have mentioned everything I did. Years ago I was a bike mechanic so I know the basics. I did play with cable tension and that is not the issue. If I am in my second from lowest gear and I push on the dérailleur, it will move to the next gear and as long as I hold it it will stay there. If I do the same with the shifter it will stay in the gear until I release pressure on the shifter. The next stop is the LBS, but I would like to know if anyone has seen this issue with red.
