About us

My name is Jeff Jones. I'm a cyclist committed to the non-suspended bicycle. My ideas and passion have created an exceptional ride - a trail-blazing geometry that delivers superb handling, comfort and efficiency. My bikes are available in titanium and steel, to be ridden off-road (and on) for exploring and racing, adventures and fun. They are outrageously responsive bicycles - frame and forks designed in harmony to provide a rigid bicycle that is anything but. A pure cycling experience like no other.

Jones Spec. Schrader Valve Stem (pair)

Schrader valves are stiffer, sturdier and easier to use than presta valves. They have a larger diameter than presta valves allowing for increased airflow and this makes setting up tubeless tires much easier. The 36.5 mm long valve stems work perfectly with Jones aluminum and carbon rims and wheelsets. They also fit many other rims as well. The aluminum base of the stem is smooth, rounded, and lower profile which makes installing tires easier without catching the tire bead on the stem. The large inside diameter features a beveled, all metal opening for faster/higher volume airflow and no clogging. The large valve stem ring nut has more surface area for your fingers making it easier to turn. It also has an o-ring to keep it tight. The valve cores are removable and replaceable. Sealed aluminum valve caps top everything off and even come with their own integrated tools. One cap is a valve core removal tool and the other is for bleeding air.

Why use Schrader?

Schrader Valve vs. Presta

For very narrow rims, smaller diameter presta stems are used so a smaller hole can be made in the rim. A larger diameter hole could make the skinny rim weaker there. For wider rims, the Schrader valve stem makes more sense. The Schrader valve stem is stiffer, sturdier and easier to use than presta. They have a much larger diameter than presta allowing for increased airflow. This makes setting up wheels tubeless much easier.

Presta valves use the air pressure in the tire to close the valve and a small nut to lock it shut. If the valve nut is left loose on a bike that is running very low pressure, the centrifugal force at high speeds is enough to open the valve and let air out. The small nut is also easily damaged if you do not install and remove the pump head correctly when inflating your tires. Many failures happen on the trail when using small frame pumps that do not have flexible hoses. The small nut often bends or breaks off.

With Schrader stems, a spring keeps the valve shut. This is much better for low pressure use. When pumping up your tires, the pump nozzle depresses a pin, opening the valve and allowing for airflow. It is much more robust and less prone to being damaged.

Another reason we prefer Scrader to Presta is the increased airflow. The inside diameter of our Schader valve stem is much larger than presta! This greatly increases the amount of air flowing into your tire making setting up tubeless and seating tires much easier.


  • Remove the cap, nut and o-ring from the valve stem.
  • Insert the valve stem through the valve hole in the rim.
  • Put the o-ring on the valve stem and tighten the valve stem nut until the valve’s rubber bushing seals tight against the inside of the rim.
  • Always screw on the integrated tools/caps after inflating the tires so you have your tools with you and to keep dirt and debris out of the valve.
  • For best results when setting-up your wheels tubeless, remove the valve cores. This will more rapidly inflate your tires making the tire beads pop on to the rim's bead seat quickly and easily.
