2016 Schwalbe Presta Valve Extension RVC 17 mm (pair)
For over 70 years Schwalbe has dominated the two wheeled tire industry in Germany and Europe and they now offer an equally high quality valve extension for today's aero rims. These extensions are great because they fit inline on the valve between the valve core and existing valve stem. Rubber seals keep the air in but Teflon plumbers tape can be used to further strengthen the seal. A tool is included for valve core and extension removal/installation. They can be used with any tubular tire or tube with a removable valve core.
Aluminum. Each extension weights only 1.0 gram (measured).
