They have, and I also do in between visits. After the first replacement, they only have their master wheel guy work on it. As referenced many, many times in this forum, there is an issue with the CrossCurrent's spokes that Juiced seems to be aware of, but doesn't want to offer any actual solutions other than 'just keep buying our spokes that either don't fit correctly, or are made of low-quality metal'.
$250 was their high estimate - LBS is still figuring out what spokes they can get, but I told them I wanted the strongest spokes within reason, so I'm expecting I'll have to pay $4 a spoke, 36 of them, plus an hour of labor is going to be around $200 minimum. With the weird size of the spoke, it may drive cost of the spokes up even further. I will NOT use any more of Juiced's spokes.
