I have been exploring different avenues for my commuter bike. I currently have a road bike that is setup more for performance and I do not intend on converting it to a commuter for a myriad of reasons. I'd like to build up or purchase a bike specifically for commuting purposes.

If I don't go for the complete bike route, I would purchase a frame and build it up. I would like to keep it under $1500, preferably $1000 if possible. My confusion lies mostly in the groupset choices. I have SRAM Rvial on my roadbike and don't need anything that nice (though I know it [strike]is[/strike] was the cheapest SRAM offering) on my commuter.

For the frame I was thinking of a Civia Bryant or Hyland, Soma Doublecross, or Surly Crosscheck. I am sure there are others too, so feel free to suggest.

I am particularly interested in the new SRAM Apex offering. It seems to be about $700. What does it compete with? Is it in the same category as Tiagra or 105? I read it's actually comparable to the upcoming 105, which is confusingly called 5700.

I also understand I could mix and match but it's not like I have some parts bin with random components sitting around. I also assume it's cheaper to buy as a set.

About my ride:

Paved roads with bike lanes and MUP
Weather: Avg high 64-75F, avg low 40-58F
Rain: 0-3.6 inches
Distance: 2-25 miles
Not too hilly

As you can see, I pretty much live in paradise (weather wise). I am not sure how this affects groupset decisions, but I thought I'd include it. I definitely know it will affect my tire and fender choices.

Thanks for your help.
