Yes a compact. I'm a little disappointed. Clearly, I was too focused on the final product to absorb all the details. I'm fairly certain that I'm going to switch out the compact for a standard. I was riding in 50/12 today and felt like I could crank more.
50-11 is lower the 53-12. An 50x34 with a 11x23 is about the same is a 53x39 with a 12x25. You can check it out on Sheldon Brown's web site.
