Escape presents theTubolito Tubo CX/Gravel 700/650B Presta 42mm Inner Tube, a 700c/650B inner tube that offers unique versatility for CX and Gravel riding. Its thermoplastic material makes it significantly lighter and more Compact than butyl, while providing improved puncture resistance—ideal for cyclists looking for a universal, high-performance spare.
Features:
- Valve: 42mm Presta valve. This is a standard valve length, suitable for most Gravel and cyclocross tires, making inflation easy.
- Material: Made from a high-tech thermoplastic elastomer (TPU). This material is the foundation of its lightweight, durable, and compact properties—and, crucially, its high elasticity, which allows compatibility with two wheel diameters.
- Tire Compatibility: Thanks to its elasticity, it is compatible with a wide range of tire widths typical for CX and Gravel, generally from 700x30C to 700x50C (or the equivalent 650B x 1.2" to 2.0" and ETRTO ranges such as 30-622 to 50-622 or 30-584 to 50-584).
Advantages:
- Dual-Size Versatility: Its main appeal is its ability to fit both 700c and 650B wheels, making it incredibly practical as a universal spare or for riders with multiple Gravel/CX bikes.
- Lightweight: It is significantly lighter than equivalent butyl tubes (often up to 60–70% lighter). This reduction in rotational weight can improve the bike’s feel on mixed terrain and enhance acceleration.
- Compact: Its material allows it to fold down to a much smaller size than butyl tubes, taking up less space in your tool bag or jersey pocket—ideal for long Gravel rides.
- Improved Puncture Resistance: It offers greater puncture resistance than standard butyl tubes, making it more robust against punctures from sharp objects on off-road terrain.
- Low Rolling Resistance: The thermoplastic material contributes to lower rolling resistance compared to butyl, which can result in greater pedaling efficiency on various surfaces.
