The Continental MTB 26" inner tube with Presta 42 mm valve embodies the technical excellence of Continental, world leader in tire technologies. Designed for demanding mountain bikers, this high-quality butyl inner tube guarantees optimal airtightness and superior puncture resistance. Compatible with 26 x 1.75" to 2.50" tires (ETRTO 47-559 / 62-559), it adapts perfectly to All Mountain, Enduro and Trail riding. Its removable valve core facilitates inflation and the addition of liquid sealant.

Technical highlights

• Seamless vulcanized construction: The molded-vulcanization technology eliminates weak points, ensures perfect roundness and improves valve insertion reliability. This construction guarantees smooth rolling, consistent performance and increased durability.
• Threaded Presta valve 42 mm with removable core: The valve features a lock nut at its base that eliminates all valve movement during braking, significantly reducing the risk of puncture by cutting near the valve. The removable core allows rapid inflation and the addition of liquid sealant.
• High-performance butyl: The Continental butyl compound offers the best compromise between light weight (200 g), puncture resistance and pressure retention over time. Each tube undergoes 100% quality control at the factory.
• Extended compatibility: Fits all 26" MTB tire widths from 1.75" to 2.50", i.e. ETRTO sections from 47 mm to 62 mm (47-559, 48-559, 50-559, 54-559, 55-559, 57-559, 60-559, 62-559).

Use and recommendations

Recommended use: MTB all disciplines (Cross-Country, All Mountain, Enduro, Trail), off-road touring bike, light fatbike. Installation tip: Inflate the tube slightly before mounting to avoid pinching, check for foreign objects in the tire and rim, and use talcum powder to facilitate positioning. Recommended pressure: follow the tire sidewall markings (typically 2 to 4 bar / 30-60 PSI for MTB). Maintenance: regularly check pressure (butyl is naturally permeable to air over the long term) and inspect the valve before each major ride.
