Continental Tour 28 (700c) 32-47 mm (622-635), Presta 42 mm Inner Tube

The Continental Tour 28 is a classic inner tube for 28-inch and 700c wheels with slightly wider tires. It fits 700c tires from 32 to 47 mm and is a reliable choice for touring, commuting, and everyday cycling when you want a standard butyl tube with good puncture protection and low weight.

This version has a 42 mm Presta valve, also known as a racing valve. The valve length suits most standard rims with a low or moderate profile. If you have deep-section rims, check that a 42 mm valve is long enough for the pump to connect properly.

For standard 700c wheels, the tube's ETRTO range is 32-622 to 47-622. Continental also lists compatibility with 42-635. If you're unsure, check the ETRTO marking on the side of your tire - both the tire width and rim diameter need to match the tube's stated dimensions.

Every Continental Tour 28 undergoes quality control before leaving the factory. A simple and reliable choice for bikes with wider 700c tires when you still want to use a traditional inner tube.
