20", 406

This presta tube in particular fits tires from 28mm to 32mm. Even though it's pitched as the right tube for the Continental Gran Prix, it's fills the tire completely. This means take care when putting this tube in to avoid pinch flats. All Continental tubes are seamless and mold-cured (vulcanized) to ensure uniform roundness and improved reliability at the valve stem. Each and every tube passes a stringent 100% quality control inspection

Designed for an 18" wheel, this tube also works very well for narrow 20" (406) applications. We've used this tube for years in Gran Prix and Stelvio tires on narrow rims. In presta only. Many guys have gone with this over the years because it seemed to be the only tube narrow enough to handle the 28mm 406 tires. The Continental tubes were too fat even though they stated they were for the Gran Prix. However, the Schwalbe tubes (AV6 & SV6) fit both the Gran Prix and Durano/Stelvio very nicely.

Quality tubes in every size for 406 and both presta and schrader.

Need a little extra protection? We stock puncture resistant 20" tubes for a few of the larger sizes and schrader valves. These tubes are basically three times as thick as a normal weight tube. In many cases, you can make your bent virtually impregnable to flats with these tubes, a tire liner, and a tire like a Marathon or Marathon Plus

Extremely air-tight! Less air loss means having to inflate less often. Our unique rubber mixture makes it possible. Extremely reliable! Each SCHWALBE tube is individually examined twice at the factory to ensure air-tightness. Special quality control that prevents unpleasant surprises. In Schwalbe talk, the SV is presta and the AV valve is Schrader.

Available in 1.25 and 1.5 width. The 1.5 is also available in a super tough tandem version. This 100psi gem is a great tire. It has a very minimal tread for good rolling ability. The laser cuts provide good traction for a fast commutting tire.

A no compromise 20 x 1.35 tire. It's home is on the road whether it be a trike or two-wheeler. Although the fast, sporty, tread-less slick weighs under 290 grams, it still has a Raceguard protection belt. Available in folding or wire bead.

The original. A high quality touring tire. Now completely revised: GreenGuard. The highly elastic, India rubber layer is 3 mm thick. Other manufacturers call such a tire “Plus”. However, Green is not just the colour, but also the philosophy: One third of the GreenGuard is made up of recycled latex products. „Anti-Aging“. The completely new sidewall construction can withstand for much longer the typical cracking resulting from overloading due to insufficient inflation pressure. Also the new Endurance Compound substantially increases durability. E-Bike Ready. The new Marathon has been designed for use on all types of E-bikes. The following sizes bear the ECE75 mark, suitable for use on faster, up to 50 kph, E-bikes.

A 20 x 2.00" tire devlivering an incredibly cushy ride. Nothing like built in suspension. In fact, we've done quite a few Big Apple's on trikes for this very purpose. Max inflation is 70psi. Big Apple - Big Ride.

A new breed of Marathon optimized for Speed and grip. The Racer features lightweight sidewalls making the Racer flexible during turns and minimizes rolling resistance. A raceguard belt protects against punctures while you're blistering along at warp speed. Available in both wire bead and folding bead.

The SportContact in a 28mm turns any bike into a racer. All this added speed for your bike with zero detriment to puncture protection and reliability! Extremely fine and strong carcass plies, SafetySystem and puncture protection are all integral features of the Contact tire family. 80 - 85 psi recommended pressure.

A 280 gram road tire for recumbents. Available in many popular recumbent widths for 406 wheels, this tire has been an industry standard for years. The 1.35 version inflates to 100psi. With it's minimalist herringbone tread, the rolling resistance is very low. A kevlar lined version is available in most sizes.

The first special tire for tricycle recumbents. Tire construction and profile contours are coordinated with the special requirements of a multi-track vehicle in mind. Tricycle recumbents exert completely different loads on tires than conventional bicycles. Nevertheless the tires must be light and fast, because drive is still achieved through muscle power and should therefore be as effective as possible. Massive motor vehicle tires are out of the question. The Tryker takes on the challenge of minimal rolling friction and high durability for the recumbent tricyclist. It has ECE-R75 certification for faster E-Bikes.

A tough tire equipped with Smartguard layers made from a flexible, special rubber. This compound offers particular resistance to shards of glass and thorns. It weighs in at 580 grams and has a max pressure of 95psi. Available in both a 1.35 and 1.75 width!
