Zipp Speed Weaponry has introduced the new lightweight Zipp Tangente butyl road tube, designed to improve rotational stability by decreasing rotational mass at the valve body. According to the company, the new Zipp Tangente tube features the only aluminum presta-valve body on the market (37mm length with removable valve core). To complement the tube, the new integrated Zipp aluminum Valve Extenders are available in lengths for each Zipp wheel.
The new tube-and-extender system puts the removable Presta-valve core at the end of the extension for the most effective air seal. That provides the same access to the valve top as with an ordinary stem. Users simply access the top of the Presta valve directly, just as on a tube without an extender.
Zipp’s new valve extender system requires three components, each sold separately, making extender choice possible based on the preferred wheel set-up. Also, as the company points out, an all-in-one valve extender kit will be in stock soon:
Zipp Tangente Tube with Removable Core (US$10)
The butyl tubes are 700c x 19-23 mm Presta 37mm and weigh 89g without the extender. The butyl tubes feature an aluminium valve body to save weight, allowing a tube thickness of 0.85 mm to optimize durability. The lightweight valve body also provides increased rotational stability.
Zipp Integrated Valve Extenders (US$9)
Made of lightweight aluminum, 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. The Integrated Valve Extenders are available in four sizes for Zipp wheels:
- 27mm (1g) for 303 model wheels
- 41mm (2g) for 404 models
- 65mm (4g) for 808 models
- 91mm (6g) for 1080 models
(Sizing note: Due to the shorter 25mm length of the Tangente Tubular Valve stem it is recommended to move up one size of valve extender to allow enough extender coming out of the rim.)
Zipp Valve/Extender Wrench Set (US$7)
Each set has two 4mm and 5mm wrenches required for assembly. The tube-valve body and extenders have wrench flats for easy removal and installation.
Available in March, comes the Zipp Integrated Valve Extenders and Valve Wrench Set (US$25). Each complete set includes three Zipp valve extenders and two Zipp valve/extender wrenches for an all-in-one kit:
- 27mm (1g) for 303 model wheels (quantity 3), and 4/5mm valve wrench (quantity 2)
- 41mm (2g) for 404 models (quantity 3), and 4/5 mm valve wrench (quantity 2)
- 65mm (4g) for 808 models (quantity 3) and 4/5 mm valve wrench (quantity 2)
- 91mm (6g) for 1080 models (quantity 3), and 4/5 mm valve wrench (quantity 2)
Zipp’s new Integrated Valve Extender is compatible with other tubes and tubular tires with removable valve cores. While, Zipp’s Tangente Tube with Removable Core is compatible with other removable-valve-core-compatible extenders.
A small amount of grease is required to seal the threads of the valve extension and valve core. The extensions include an instruction manual and require the Zipp valve/extender wrench for proper assembly.
