Familiarity: I've put it through the wringer
These X1 carbon wheelset that’s snappy, and durable all at the same time. I rode these for a couple of months on some pretty fast and rough tracks and found the wheel's ability to roll through these very impressive. The hubs have great engagement plus they’re smooth rolling. Love the silver fiber X streak. They look great!
