This Continental Mountain Inner Tube is designed for mountain bikers seeking reliable performance on varied terrain. Its seamless butyl rubber construction ensures a uniform shape for consistent riding, while the Presta valve offers a secure seal. A potential drawback is its specific size compatibility, so ensure it matches your wheel and tire dimensions before purchase.

This tube is designed for 29-inch mountain bike tires with an ETRTO size of 47/622 and a width range of 1.75 to 2.5 inches.
It features a Presta valve, which is common on performance bicycles and has a narrower diameter than a Schrader valve.
Check the sidewall of your tire for the ETRTO size, which should read '47-622' or similar, and the width in inches (e.g., 29 x 2.1).
No, this tube is specifically designed for mountain bike tires and may not fit correctly or perform optimally on road bike wheels.
The inner tube weighs approximately 200 grams.
This is a standard inner tube. While it can be used in a tubeless-ready rim with the appropriate sealant and rim tape, it is not a tubeless-specific product.
Ensure the Presta valve core is not loose and that your pump is correctly attached to the valve.
Check for pinches between the tire and rim, or for a puncture. Inspect the inside of the tire for sharp objects.
This may indicate an improperly seated tube or tire. Deflate and re-seat the tube and tire carefully.
Ensure the valve stem is protected during inflation and is not being stressed. Replace the tube if the stem is compromised.
Compatibility: This inner tube is specifically designed for 29-inch mountain bike wheels. Ensure your tire's ETRTO size is 47/622 and its width is between 1.75 and 2.5 inches. The valve type is Presta.
Setup:
Care: Regularly check tire pressure before rides. Inspect the tube for signs of wear or damage during tire changes. Store spare tubes in a cool, dry place away from direct sunlight and sharp objects.
