I have a new bike (Specialized Secteur) with less than 200 miles. It has an SRAM Apex RD with an 11-32 cassette.

I started experiencing some problems with shifting on the smaller cogs, it would either not shift or skip a ring. So I adjusted the cable tension with the barrel adjuster according to the park tools site. I can get the smaller cogs shifting ok, but then I can't shift onto my large cog. If I adjust the tension to get my large cog, then I have problems with the smaller. I don't think my "L" stop is bad, I set it per the park tools site and I can shift onto the large cog just fine with more tension in the cable (or if I just pull on the cable).

Any clues? It goes into the LBS for a tuneup next week anyway, but I'd like to be able to do simple adjustments like this.
