We flow-test ten tubeless valve stems.
We flow-test ten tubeless valve stems, including Presta and Schrader to see the differences and to find the stem with the most flow because tubeless valve stems with a higher flow rate make mounting tires tubeless easier.

NEW: Jones LWB Complete Bike, A Bike For Riding
Jones Schrader tubeless valve stems have a larger inside diameter which gives them more flow than high-flow Presta valve stems and other Schrader stems. It’s also lighter than many Presta valve stems.

So, why use Presta?

Jones Spec. Schrader Valve stem.

Jones Spec. Schrader Valve Stem description (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 making 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.

Jones Bikes has switched from Presta to Schrader on all bikes and wheels!

After comparing and testing Presta and Schrader valve stems, it makes sense to change from Presta to Schrader.
