So, I just got a new pair of 2005 Ksyrium SLs; I've put many thousands of miles on Ksyriums with no problem, but having put about 150 on these new hoops I've found that the rear hub occaisonally makes a loud popping sound when I pedal hard out of the saddle. This corresponds to a slight skip in the pedal stroke, and I think it's that the pawls are slipping a tooth in the freehub. I opened up the freehub, and there's nothing obviously wrong, the pawls look good and there are no metal splinters or anything. Anyone had any experience with a similar problem? Any suggestions? Lube/grease em? I've always used mineral oil on my K's...
