MAXXIS - MODULAR VALVE SYSTEM
Maxxis Modular valve tubes allow you to easily customize your bike.
The separation of the tube and valve stem allows you to chose your valve length and custom colour without having to deal with finicky valve extensions.
When the tube eventually has to be replaced, the valve stem transfers to the new tube, instead of ending up in the rubbish.
Stems will not fit a standard tube.
