![]() ![]() ![]() Let’s keep it real, though: we’re only talking about the difference of a few millimeters here. For example, type ‘no-clog tubeless valves’ into your favorite search engine, and you’ll find versions like the Industry Nine No-Clog Aluminum Tubeless Valves, which boast a higher interior lip, purportedly to help reduce sealant from over-splashing and reaching the core. Like any other cycling product, you’ll find minor design differences between tubeless models from different manufacturers, even when it comes to something as simple as a valve. With these details in mind, can you buy tubeless bicycle valves that resist clogging? What’s the Difference Between Standard Tubeless Valves & No-Clog Valves? Instead, with a removable core, you can simply unthread it from the valve’s body and clean or replace it, instead of changing out the entire valve altogether, which could quickly become expensive and time-intensive. In other words, the same chemical reaction that quickly plugs holes in your tires and prevents too much air from leaking is the same one that eventually clogs your valve’s core, regardless of the brand. Second, whether Schrader or Presta, the problem with most commercially available tubeless setups is that the sealant is a little too good at its job. Presta valves feature a threaded body that accommodates a tightening nut, as well as removable/replaceable cores for ease of maintenance.Īs BikeRadar’s Billy Eich argues, though, the rationale behind Presta’s carte blanche within the tubeless world has come under scrutiny as the cycling industry grows, since Schrader valves are more common, offer greater durability, and perhaps most importantly, are increasingly available with removable cores.īut, why are removable cores such a big deal? First, with its core removed, a tubeless valve can accommodate greater airflow, which is a considerable advantage when seating tubeless tires on rims. Although it’s certainly not universal, Presta valves also often feature removable valve cores for ease of maintenance.The valve body’s exterior is threaded, which allows for the addition of an external nut that tightens against the rim and further seals the rubber base into its hole.In most instances, tubeless setups utilize Presta valves for two commonly-accepted reasons: Riders often add a small amount of liquid sealant inside the tire, such as Orange Seal or Stan’s NoTubes, which feature nanoparticles that are immediately pulled to holes as air escapes, and then quickly coalesce to prevent additional air from escaping. Without an inner tube, a tubeless valve relies on a small rubber base attached at its back to maintain air pressure inside tires. But, how can we remove inner tubes from the equation while maintaining an airtight seal between the rim and the tire? Let’s continue in the next section. The problem, as anyone who’s ridden a bicycle long enough will attest, is that inner tubes are prone to puncture and air loss, which can quickly ruin even the best rides. ![]() ![]() In this image taken from our Bike Pump Buyer’s Guide, we can see the fundamental design differences between Schrader (left) and Presta (right) valves. ![]()
