A small part that saves real grief. SILCA's Presta valve cores are CNC-machined brass with roll-formed threads and fully synthetic seals, so they resist sticking, ageing and sealant damage for far longer than typical cores.

Highlights

  • 6 valve cores plus 1 removal tool
  • CNC-machined brass with roll-formed threads
  • Spun-formed top stops the valve nut unthreading too far
  • Fully synthetic stem and core seals resist ageing and sealant

Why they're better

Most cores have crimped threads at the top, which can damage them so the nut won't thread over. SILCA's cores have a spun-formed mushroom head that keeps the threads intact. Synthetic seals hold up better against both synthetic and natural-based tubeless sealants.

Compatibility & fit

Presta valve cores. They replace or upgrade the removable cores in tubeless valves, tubulars and high-end clincher inner tubes. The valve must have a removable core.
