Inner Tube Valve Extenders

Velodrome Shop


Our lightweight valve extenders convert a standard length Presta Valve into a XL valve in either 48mm or 72mm options.

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.)

  • Lightweight, precision CNC alloy.
  • Size options: 48mm or 72mm.
