The Quarq TyreWiz 2.0 Valve Stem Pack takes the guess work out of the tyrewiz/ tube stem variations. I found that I would have to judge how much tightening I had to do to secure the Tyrewiz 1.0 to the manufacturer's tube stem. This caused air leakage if the tube and the tyrewiz 1.0 were not the same depth.
Got these for my sensors, mounted to Hunt wheels. They work great with the sensors, easy to install, holds air good as regular valves.
