I have the Diverge Elite E5 which has an aluminum frame, but a carbon fork. There are attachment points for a rear and front rack and I already installed a rear rack. It's just the specific front rack that I'm having an issue with. I may have to look at other front racks. The last tour I took, which was on a different bike, I was carrying about 15 lbs spread over 2 front and 2 rear panniers. I definitely noticed the effect on handling, but it was very manageable. I'm expecting it to be similar on the Diverge.
