I have a 2009 Motobecan with carbon seat stays and no eyelet for a rack (old ****ty photo below).


I am doing a little three day 250mi self supported ride next month (St. Paul to Ely, MN) and I need to plop a rack on this bad girl. I have a spare aluminum Planet Bike rack that I was looking at using. I did do some research on solutions and most have come up with using p clamps or buying a new rack and quick release mounting gear (I really, really don't want to spend an extra $150). So here's where I get a little queasy about using p clamps, I'm really not too sure about about putting 25lbs+ of weight on the carbon fiber seat stays in a spot they were not designed to transfer weight.

Are my fears unjust or is that weight going to be too much in a bad spot for the carbon fiber to handle or is there another way to mount this that circumvents putting the weight on my seat stay?

I should also note am a big rider, 6'2", 210-220lbs depending on the day.
