Silca's replacement Presta valve cores were developed alongside its tubeless valve stems and are made to last. They are fully CNC machined with roll-formed rather than crimped threads, so the valve nut threads back on cleanly, and a spin-formed mushroom head stops the nut unthreading too far.

The stem and core seals are fully synthetic, so they resist ageing and cracking and stand up far better to both latex and synthetic tubeless sealants.
