The Dolce Comp has SRAM Apex and the other bikes had Tiagra and/or 105. The LBS guy said that even though the Apex was a lower end SRAM, it was about even with the midline Shimano. At least that is what I inferred.

I've ridden 4 or 5 bikes this week. Except for the Comp, they all had Shimano. The Comp also comes with the 105, but by then I would just get the Elite.
