While I'm on this board with my derailleur question, I also have a question about tightening loose spokes on the Ksyrium SL Wheels. I have had these wheels to two bike shops and I have had a few friends who are pretty proficient at truing wheels try to fix this wheel, but all they seem to be able to do is tighten the spokes slightly. I have been told that there is corrosian in the nipple and it won't turn enough to tighten the spokes. One mechanic said that he used some kind of libricant and was able to tighten them a little more, but it would take some time.
Do any of you have any suggestions about ways to tighten the spokes or know of any ways to clean out the nipples? Can the nipples be replaced on these wheels to resolve the problem?
Thanks in advance!
