So there I was, just at the end of a group ride, and i hear POP! At first I thought that it was something that my tire hit, but then it dawned on me that maybe my 3 month old Ksyriums may have a had a problem.

So I stopped and checked, and sure enough, one of the spokes on the cassette side of the rear wheel had come loose at the screw in nipple. Needless to say, it was a VERY long ride home. 13 kms in 50 mins.

So, my question - is this an easy enough fix?

I'm clueless with wheels, so they're going to the ol' LBS

TIA
