Okay, went back to REI. They were extremely patient and understanding, stating that they understand my hesitancy to ride it with the carbon chipping. They offered to A) do a full exchange for a Cannondale Topstone 2 they had in the store B) start the warranty process with Salsa, estimating 2-3 weeks to get the part and put it back together. I went with option B, but now, of course, I'm second-guessing because I was planning to ride some really nice gravel on a vacation next week and won't have a bike.
