The Cinturato SmarTUBE X is Pirelli's toughest TPU tube, made for endurance rides and gravel adventures. At three times the thickness of a standard SmarTUBE it's extremely protected, while still saving weight and space over butyl. Available in 700 X 28-40C and 700 X 40-50C.

Highlights

  • Three times thicker than a standard SmarTUBE
  • TPU: stronger than butyl as a raw material, up to 70% weight saving
  • Around 50% more compact than butyl
  • 60mm black Presta valve

Protection

The extra thickness makes it highly resistant to punctures, so you can take on rough terrain and conditions with confidence.
