It's been a while since I originally posted on this thread - so I thought I'd update everyone. I had been using my standard Cross cranks with an 11-28 Cassette. It worked pretty well but I still felt like I was always in the lower end of the gearing with all the hills I have where I live, or I ran out gear on some fast road rides. I just switched out my chainrings from FSA 46/36 to FSA 48/34. So far, I'm extremely happy with the decision. The 34 chainring is perfect for trail riding and gets me up just about any hill I encounter while remaining seated. The 48 provides a very good gear for the road too. Shifting is perfect - leave it to FSA. I'll see how it performs this year in cross races - but for my level, I don't really think it will make that much of a difference - and 80% of my yearly riding is on the road anyway - so I feel I have the best mix now.
