I bought a pair of Kysiriums ssl and have found them very good. After about 1 month on them I and others riding beside me heard a clicking noise and could not find out where it came from. Bottom bracket was repacked, can't be coming from the new hubs or not. Bike shop could not find the problem and for another two weeks nor could I. Back to the shop again for them to ride and yes it was coming from the bottom bracket or the hubs. Almost ready to go in and get the work done when another rider said he had the same problem with another different pair of wheels.
We took off the tire and put plumbers tape around the value and guess what no more noise. It appears that if you use the medium stem and not the long stem you will have noise. I changed to the long stem and without tape and good as gold.
This is just some information to others that hear a clicking nosie as the wheel goes around to check this before major work is to be carried out.😉
