Review on Revolutionary Colby Valve Permanent Stem Replacement - Effortless Installation from Outside the Wheel! by Chris Horton
Expensive but high quality and easy to assemble.
Expensive but works well. 6 months old and holding up strong. Easy to set up and even the jack didn't come off the ground which was flat due to the broken barrel. Installed, inflated and still holding air.
Pros
- Decent performance
Cons
- Clarity
