Escapa presents theTubolito S Tube CX/Gravel All 650B/700 Presta 42mm inner tube, designed for CX and Gravel bikes and compatible with 650B and 700c wheels. Its advanced thermoplastic material makes it extremely compact and offers improved puncture resistance and low rolling resistance, optimizing performance on mixed terrain.
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 key to its extreme lightness, compactness, elasticity for dual-size compatibility, and improved durability.
- Tire Compatibility: Thanks to its high 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:
- Extremely Lightweight: It is one of the lightest tubes in its class, with a typical weight of only about 30–40 grams. This dramatic reduction in rotational weight improves the bike’s agility, acceleration, and overall sense of speed on mixed terrain.
- Ultra-Compact: Its material allows it to fold down to an incredibly small size (often half the size of a butyl tube), taking up minimal space. This makes it ideal to carry as a spare on long Gravel rides or during races.
- Improved Puncture Resistance: Despite their light weight and thin profile, S-Tubo tubes offer superior puncture resistance compared to conventional butyl tubes, thanks to the inherent strength of TPU.
- Low Rolling Resistance: The advanced material and optimized construction contribute to lower rolling resistance compared to butyl, resulting in greater pedaling efficiency and a feeling of increased speed on various surfaces.
