The Continental Tour 28 All inner tube is the versatile and reliable solution for all urban cyclists, touring cyclists and gravel enthusiasts. Made from premium butyl, this 700C inner tube fits a wide range of tire widths (32 to 47 mm) and guarantees optimal airtightness, puncture resistance and extended pressure retention. Equipped with a 42 mm Presta valve with removable core, it facilitates inflation as well as the addition of preventive sealant.

Technical highlights

• Vulcanized seamless construction: Individually molded to ensure a perfectly round and uniform shape, the Continental Tour 28 inner tube guarantees smooth, consistent rolling without unwanted vibrations.
• Premium butyl material: Recognized for its excellent air retention, high-quality butyl limits pressure loss and extends the time between inflations, ideal for long rides and daily use.
• Removable Presta valve (42 mm): Thin high-pressure valve with extractable core, compatible with all Presta pumps and allowing the installation of extenders or injection of preventive sealant.
• Versatile use: Compatible with city bikes, hybrids, trekking, gravel, cyclocross and even some 29-inch MTBs, this tube adapts to all terrains, asphalt or trails.

Compatibility and standards

The Continental Tour 28 All inner tube conforms to ETRTO standards 32-622 to 47-622 and 32-630 to 42-635, corresponding to common dimensions 700x32C to 700x47C, or 27 x 1¼ to 28 x 1¾. It thus covers a very wide range of tire widths, from 32 mm (wide road tires) to 47 mm (gravel or trekking tires). The 42 mm Presta valve is suitable for classic low or medium profile rims (up to approximately 30 mm in height). For higher rims, Continental offers versions with 60 mm valves.

Continental quality and reliability

Manufactured under strict quality control with 100% inspection of each inner tube, the Continental Tour range benefits from decades of expertise from the German tire leader. The vulcanized mold construction guarantees optimal resistance to heating, deformation and micro-perforations. The butyl used offers an ideal compromise between lightness (approximately 170 g), flexibility and longevity, for intensive worry-free use.

Recommended use

This inner tube is specially designed for bicycle touring, urban bike commuting, gravel and cyclocross. It is perfectly suited to cyclists looking for a durable, easy-to-install solution requiring little maintenance. Whether for daily urban commutes, multi-day tours or mixed-terrain rides, the Continental Tour 28 All meets the requirements of reliability and comfort. It easily fits in a saddle bag as a spare tube.
