Review on Gray Presta Valve Core Extender by Jason Connolly
Buy it if you have a Zipp 808
Loved it. I wrapped some thread sealing tape around the extension before inserting it into the tube valve and did the same with the valve cores. Pump up the air and then check for air leaks before I put it in the wheel. Worked great.
Pros
- GRAY's latest custom designed valve extenders are now for "built in" use
Cons
- There are downsides
