I'd ask the bike shop you purchased the Domane from to see if they can warranty the wheel as a rim should be able to last longer than 5,500 miles. I had a similar issue with the RLs that came with my Domane; I got about 5,000 out of the rear and 8,000 out of the front before the eyelets started cracking. After five warranty wheels (yes, five, I ride a lot), Bontrager finally just upgraded me to the RXLs which have lasted nearly 20,000 miles now.
