Seriously, the CR18 is the most insane durable rim I've used, outside of the bomber hoops on my enduro racer. I've been using a pair of CR18 mirror polished 32h hoops on DT Champion spokes for the past 4 years of randonneuring and year-round commuting. These are the longest lasting rims I've ever had. They're currently sitting at over 14,000 miles, whereas previous rims (DT Swiss RR1.1, Alex DA16, IRO Cold Fusion, Mavic Open Pro) have barely lasted me past 8,000 miles.
