I noticed last a very irritating rattling noise when I used my ZIPP 909 wheelset last night for a 10myle TT. I have noticed it before but ignored it. As this set is only a month old with not that many miles on I investigated after the TT to find out what is causing it as I must admit one of my pet hates is rattles! I then discovered that the carbon bits between the hub and the QR are basically just loose part and these move freely around. When riding these rattle against the metal hub and makes a very annoying noise… Anybody noticed this on a ZIPP front wheel?? Second thing when I inspected my 909 rear disc I noticed that when I turn it it sounds like there are some bits inside in the hollow compartments moving.. almost like sand moving. Is this common or should I worry about the wheel falling apart on the inside?
