Zipp 60mm Valve Core Extension

Works with Zipp butyl inner tubes with a removable core as well as other leading tubular tyres and inner tubes that have removable cores. (Important note: These integrated extenders are NOT compatible with Zipp Tangente Tubular Tyres. Those tires use the older Zipp Valve Extenders.) For ease of use the core is located at the end of the valve extender. Made of lightweight aluminium, and featuring an integrated air seal, the extenders are designed with the same attention to detail and performance that’s built into Zipp wheels and other products.
65 mm (4 g) for 808 models.
