Continental Tour 28 (700c) 32-47 mm (622-635), Schrader 40 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.

This version has a 40 mm Schrader valve, also called an auto valve or car valve. It's the same type of valve used on car tires and is commonly found on city, trekking, and hybrid bikes. Check which valve type your rim is designed for before ordering – a Schrader valve is wider than a Presta/racing valve and won't fit through a valve hole sized only for Presta.

For standard 700c wheels, the tube's ETRTO range is 32-622 to 47-622. It also fits compatible older 630 and 635 sizes up to 42 mm wide. Check the ETRTO marking on the side of your tire if you're unsure, since both tire width and rim diameter need to match.

Every Continental Tour 28 undergoes quality control before leaving the factory. A simple and reliable choice for bikes with wider 28-inch tires and Schrader valves.
