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

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 states compatibility with 42-635. Check the ETRTO marking on the sidewall of your tire if you are unsure—both the tire width and rim diameter need to match the tube’s specified 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.
