This is CST's 24 x 1-3/8 inch tube, sized to ETRTO 37-540mm, so it suits a 24 inch wheel running a 1-3/8 inch tyre. It uses a Presta valve with a 60mm stem, long enough to reach through a deeper rim.
The valve is threaded, so it takes a lock ring and a cap. Wall thickness is 0.97mm, and CST list this one as their most popular bicycle tube.
