Product Description

Alloy Presta Valve Extension, Hex Key Fiiting, Non-Slip pump fitting


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.

Occasionally, without notice, manufacturers change product design and/or specifications.

Wheels Guide

What are wheels?

Wheels are probably the second most important part of your bike, after the frame. A lot of the bike’s riding characteristics come from its wheels.

Who needs wheels?

A wheel upgrade can make a massive difference to your bike. Because of this, you might consider a new set of wheels, even if the old ones aren’t worn or damaged.

What are the choices?

Mountain bikers choose their wheels in 26in, 27.5in or 29in size, depending on what their frame is built for. Road bike wheels are 700c. Beyond this, there’s a dizzying array of rim material and depth, spoke type and hubs galore – enough to make your head spin faster than your wheels.

What should I buy with them?

A wheel upgrade always deserves a lovely new set of tyres. These too have a massive impact on how your bike rides.

Anything else?

There are several approaches to buying wheels – you can buy a full wheelset, for perfect pairing, or you can take a modular approach, picking hubs and rims before having a new set built to your specification.
