Received my set of rear spokes this morning and replaced the broken one so have to go on a test ride now.
Just over 100,000 miles and this is the first broken spoke on my 2013 bike.
I pinged my rear spokes, as I do periodically, and got a thud on one of the inner spokes. It was still in place, just the head was broken off at the rim hole.
Since the broken one was an inside spoke I still have a spare inside as well as the 2 outside spokes as spares.
Of course, OldRider color coded the end of each nipple and there are instructions to tell you which color goes where.
Thanks OldRider, you provide a great service!
