The Continental Tour 28 Inner Tubes are designed for touring cyclists seeking reliable performance on their journeys. Their key benefit is durable construction ensuring fewer flats during long rides, with a potential caveat being the specific Presta valve type which may require a different pump than Schrader valves. These 700c tubes are suitable for tire widths from 32mm to 47c and feature a 42mm Presta valve. They are manufactured using a seamless, mold-cured process for enhanced longevity.

Presta valves are thinner with a locknut at the tip, often found on road and touring bikes. Schrader valves are wider, like those on cars, common on mountain bikes and hybrids. Presta valves generally require a different pump head.
These tubes are designed for 700c wheels and tire widths between 32-47c. While a 29er uses a 700c rim, the tire widths typically exceed 47c. Please check your specific tire's width for compatibility.
Tire width is usually marked on the sidewall of the tire, for example, '700 x 38c'. Ensure the number falls between 32 and 47.
This refers to the length of the valve stem from the base where it meets the tube to the top. 42mm is a common length for touring and road bike rims.
Yes, most pumps have a dual head or an adapter for both Presta and Schrader valves. Ensure your pump is compatible before attempting to inflate.
Store spare tubes in a cool, dry place, away from direct sunlight and sharp objects. Avoid extreme temperatures. Keeping them in a small bag can offer protection.
This manufacturing process involves curing the rubber in a mold without seams, which helps to create a more uniform and durable tube with fewer potential weak points.
Ensure the pump head is securely attached to the Presta valve and the valve core is open. Check if the valve core is damaged.
Check for a pinch flat (tube caught between rim and tire bead) or a puncture in the tube or tire. Re-inspect the tire casing for embedded objects.
Ensure the tube is only slightly inflated to give it shape, not fully inflated. Avoid twisting the tube during installation.
Tighten the lockring on the Presta valve stem (if present). If the leak persists, the valve may be faulty, and the tube may need replacement.
