Won't shift on first try

[tctrek]

I do have trainer (very recent purchase) which is how I discovered that I could shift it by hand pedaling. I will try cleaning everything to see if that helps. I purchased the bike new in February so that shouldn't be the issue.

My LBS always asks me to come back within 90 days of purchase so that they can give it the once-over -- check out all the alignments and tweak stuff that has loosened up or shifted since it was new.
