Tubolito gravel tube Tubo-CX/Gravel Black (Pack-1), 27.6" x 1.3"-2" — ultra-light, puncture-resistant spare

Tubolito CX/Gravel 700C tube is an ultra-light, highly durable spare tube for gravel and cyclocross tires sized 700 x 32–50mm, available with 42mm or 60mm Presta valves.

This tube swaps the bulk of a conventional butyl spare for a featherweight, puncture-resistant alternative engineered for mixed-surface riding. Designed to save space in your saddlebag or pocket, the Tubolito CX/Gravel balances low rolling resistance with increased tensile strength so you can carry fewer spares and still tackle rough roads, gravel tracks, or long event days.

How does this tube withstand rough gravel and cyclocross conditions?

The Tubolito CX/Gravel is constructed from a proprietary elastomer that delivers roughly twice the tear resistance of standard butyl tubes. That material choice increases resilience to pinch flats and small punctures while keeping the tube light and flexible.

• About 2x durability vs standard butyl tubes
• Lower puncture susceptibility on mixed surfaces
• Flexible wall for better impact absorption

Will it fit my wheel, and what valve length should I pick?

These tubes cover a wide tire width range: 700 x 32–50mm, so they suit most gravel and cyclocross setups. Choose the 42mm Presta valve for shallow rims or the 60mm Presta valve for deeper rims and tubeless-compatible wheel profiles.

• Fit: 700C tire diameters, 32–50mm widths
• Valve options: 42mm or 60mm Presta to match rim depth
• Weight: ~60–61 grams depending on valve length

How easy is it to carry, install, and service on the road?

Tubolito tubes pack down to roughly half the size of standard butyl spares, so they slip into jersey pockets or minimal saddle packs with ease. Installation follows the same three basic steps as any tube change, and the material allows standard tire levers and pumps to be used without special tools.

• Packed size ~50% smaller than conventional tubes
• Three-step installation: remove, insert, inflate
• Compatible with common floor and mini pumps

Does this tube work with rim and disc brake bikes?

Yes — the Tubolito CX/Gravel tube is suitable for both rim-brake and disc-brake bicycles. Its fit and pressure range accommodate typical gravel and cyclocross tire setups regardless of brake type, so you don’t need separate tube choices for different brake systems.

• Designed for rim and disc brake bikes
• Maintains recommended tire pressures for gravel use
• Minimal rolling resistance for efficient pedaling

Who is this for? Riders who want a reliable, space-saving spare for gravel, adventure, and cyclocross use benefit most from the Tubolito CX/Gravel. If you value low weight, compact packing, and improved durability over a standard butyl spare — whether you race, commute, or explore backroads — this tube reduces carry weight and increases confidence without changing your pump or repair routine.
