I use 46/34 x 12/36 on my Cervelo RS. I swapped out the 50t chain ring it came with for a 46t one. This gives me nice ratios on the "big" ring for all day riding in flat and rolling terrain, and 103" is high enough for me. I went to a SRAM mountain bike derailleur that works with the 12/36 and it works fine with the Apex shifters that came on the bike. A low of 25" is fine for anything I've encountered so far.
