What Makes the X-Tubo CX/Gravel the Most Puncture-Proof Tube?

The Tubolito X-Tubo CX/Gravel All Tube is built around the brand's proprietary X-Tubo Technology, a specially developed compound engineered for maximum puncture resistance against thorns, nails, and broken glass on gravel and cyclocross courses. The result is an extremely flat-resistant tube that backs up its protection with a one-year warranty after registration covering all kinds of flats, including those caused by sharp debris.

The X-Tubo CX/Gravel fits 700c tires from 32 to 50mm and uses a 60mm Presta valve, with full compatibility for both disc and rim brakes. Despite the added puncture protection, the X-Tubo compound maintains the lightweight and compact profile that defines the Tubolito lineup, making it a serious upgrade for gravel and CX riders who have paid the price of repeated flats. If you ride aggressive terrain and want peace of mind with every pedal stroke, the X-Tubo is the answer.
