I'm 98% sure it's not the adjustment. I followed the park tools instructions to a tee and it was shifting perfectly. The problem seems to occur when I don't ride over the weekend. I can feel the derailleur sticking when I try to drop to the small front ring (not going up). After spraying with lube and wiping off the cable and just pushing it back and forth for a while (pulling the chain with my hand), it will loosen up and work fine. It's going ok now, I just hope it doesn't reoccur next monday. I guess it could also be the colder weather. This weekend I will remove the cable and clean the housing. thanks for the help
