A 53x39 with a 12x23 is way to big. I would say get the compact and maybe even a 12x25. I really like the single 42 ring set up though this year I am trying a double up front again. I also got tubulars this year so I can ride at 30-35psi. As far as the cross levers go I could not live with out them. I almost exculsivly use the tops.
