Halo Valve Extender

The simple way to ensure that you don't get caught without a spare inner tube for your deep section Aero rims.
These simple but functional lightweight retro-fit adaptors will convert a standard length Presta Valve into a usable XL valve.

The clever Woodman designed exterior profile allows for most press-on high pressure pumps to inflate without slippage.

Simple to fit:

Threads onto standard type Presta valve as a normal valve cap would do, and features an internal hex-key recess to fully tighten.

To install, release the knurled Presta valve lock 2/3s of the way along it's spindle - as you normally would to be ready for a pump to be used, and install the extensions onto the valve.
(Existing air pressure will naturally keep the valve closed and air tight - as it does with other types of valve - and pump pressure will open the valve to inflate.)

Features:

• Lightweight, precision CNC alloy.
• Anodised Black or Red finish
• Size options: 48mm or 72mm.
