She is absolutely beautiful, but it seems like the top end of your gearing is awful low. I ran your numbers through the sheldon brown site and it seems your top gear ratio is only 90. Why did you choose a 48 vs a 50 ring in front? That would help a little. I have a 50/34 compact double and the shifting is just fine on it, and I have it paired with a 12/27 rear, so for me even the 50/13 would be a tad low for the high end. If you swapped your 48 for a 50 you wouldn't compromise your low end but could get a bit more of a high end. But, what is important is that you chose gears that work best for your body! Do enjoy her, she is absolutely beautiful!!!!!!!!!!!!!
