Review on 🚲 Continental BMX and Compact Bike Tubes by Jacob Ferrarini

One of the few Schrader valve chambers with a locknut (aka lock ring) that secures the fully threaded valve stem to the rim. This feature allows the air chuck to be easily attached to the valve stem without the valve stem disappearing into the rim/tire. Schwalbe is another brand with this feature. Typically, Presta valves come with a lock nut, Schrader valves do not. Very easy to assemble 20" kids BMX bike with 57-406 tires. while it works fine. They appear to be made of thick rubber and have minimal stitching. with Continental Unittube technology.
