Continental Race 28 (700c) 20-25 mm (622-630), Presta 80 mm Inner Tube

Continental Race 28 is a high-quality inner tube for road bikes with narrower tires. It combines low weight with good puncture protection and works equally well as a regular inner tube or as a spare tube in your saddle bag. Each tube undergoes strict quality control before leaving the factory.

This version has an 80 mm Presta valve, also known as a racing valve, and is primarily intended for deep-section rims where a standard 42 or 60 mm valve would be too short. We recommend checking the rim height before purchasing to ensure that enough of the valve extends through the rim for easy pump connection.

The tube is intended for sizes from ETRTO 20-622 to 25-630, covering common narrow 700c tires as well as compatible older 630 mm / 27" sizes. Check the ETRTO marking on the sidewall of the tire if you are unsure—both the tire width and rim diameter must match the tube’s specified dimensions.
