Knock from rear hitting bumps
Moderator: robbosmans
Tring to track down a clunk from the rear when I hit a bump.
Bike is a 2013 Giant TCR 2.
Recently replaced chain / cassette / rear derailleur.
Wheelset is Kinlin X31t with BHS SL210 rear / SLF71W front hub.
I can replicate the clunk tipping the bike to the left and tapping the rear wheel on the ground.
Hubs caps are tight, wheel isn't contacting the brake pad when tapping.
Any ideas? Sounds similar to a headset knocking around.

Valve stem might be it, wrap electric tape where it touches the rim?

It just happened to me today. It was driving me nuts. One of my bodies recommended jamming some klinex between the valve stem and the rim (what can I do? we were long way from civilization...) it stopped the knocking sound.
I just put some silicon instead of klinex when I got back home
