Nucleo valvola Presta argento o nero 5 pezzi

Replacement Presta valve cores — silver or black, sold in fives, with a valve tool. When a core sticks, leaks, or won't hold pressure, this is what you swap.

Perché funziona

60-second fix instead of a new tube. If the core works loose or leaks, it usually isn't the tube — it's the core. Swap the core, save the tube.

Standard Presta thread. Fits any Presta valve with a removable core, including all Eclipse TPU tubes and most aftermarket tubeless valves.

Five in a pack — and a tool. Enough to outlast most tubes, with the right tool to install them.

Specifiche

Ideale per

• Tube and tubeless riders who'd rather rebuild a valve than replace a tube
• Mechanics who go through cores faster than tubes
• The toolbox you'd actually want with you on a long trip

What makes Eclipse different

Eclipse pioneered TPU inner tubes in 2011 — and we build the small stuff that goes with them to the same standard. Every part is selected and tested to work cleanly with TPU and with the patented all-aluminum Eclipse valve.
