Silca Replacement Presta Valve Core (Set of 6)

Silca set out to design tubeless valve stems with the same quality and attention to detail found in high-end tubular valves. After extensive research and testing, Silca discovered the best valve cores available, crafted by just a few manufacturers worldwide. These fully CNC-machined valve cores feature roll-formed threads and spun-formed tops, ensuring the valve nut won’t unthread too far—a detail that sets them apart from others that crimp the threads, causing damage.

The spun-formed "mushroom head" at the top of the valve is a sign of the meticulous craftsmanship behind these cores. They also feature fully synthetic seals for both the stem and core, which makes them more resistant to aging and cracking, while offering superior compatibility with both synthetic and natural tubeless sealants.

Best of all, this exceptional attention to detail comes at almost no extra cost compared to standard valve cores, saving you from potential headaches down the road while ensuring long-lasting performance.
