I'm confused. Is the take-away here that the lock-ring was not properly torqued and therefore the cassette loosened and the chain slipped off to the inside? As result the spokes will need to be replaced, which Boyd is going to do? The fault for the incident lying with whoever installed the cassette? Just curious.
At any rate, I can attest to Boyd's customer service, regardless of the situation I have no doubt you will be well taken care of.
On an unrelated note, when I got my fancy new Boyd wheels I threw them on my bike and got ready to race. In a shakedown cruise I noticed I was having some shifting trouble. I took it to a mechanic who told me I should never go back to whoever installed the cassette. Apparently the idiot had forgotten to install the spacer....
I didn't talk to myself for the next few hours, but I made it up to myself by making sure to give myself something nice to make up for having done such a poor job on the install.
