Have an Aeroad CFR with SRAM Red. If I had to do it over again I would get the Ultimate. In a crosswind and descending, the Aeroad is very skittish. Also it is not geared low enough for climbs greater than 10% for me. I will eventually put on a larger cassette. It is a fast bike. Also a lot of issues in first month. Shifter got loose, had to center rear brake caliper, align front derailleur and bottom bracket creaks like crazy. Never had such issues with my Merckx or Cervelo.
