📏 Specifications Valve type: SV (Sclaverand / Presta) – thin road bike valve Valve length: 42 mm Suitable for rim type: Road bike / 28″ (700c) Suitable for tire widths: 25 mm to 32 mm Material: Butyl rubber 👍 Advantages ✔ Low rolling resistance → smoother and faster riding ✔ Good puncture resistance (Continental checks every tire for air tightness) ✔ Ideal for road bikes with narrow to medium-wide tires
1. Approximately 40 grams lighter per wheel The tire is thinner (0.6 mm) than a normal inner tube. Less rotating weight = faster acceleration and easier climbing. 2. Smoother ride / less rolling resistance The thinner rubber allows the tire to deform more easily. Tests show: up to 13% less resistance per wheel →you lose less energy while cycling. 3. Talc (powder) in the packaging Ensures the inner tube slides into the outer tire more easily. Less chance of pinching when mounting. 4. Extra strong base at the valve (4.8 cm) Prevents the valve from tearing out (this sometimes happens with lightweight inner tubes). Especially nice with high tire pressure. 5. Valve works better with a pump Top of the valve is smooth → pump fits better Less wear on your pump
Airlock Presta Inner Tube – Self-sealing & Puncture-resistant The Airlock Presta inner tube is designed for cyclists who don't want to deal with flat tires. Thanks to the powerful, integrated Airlock sealant, punctures are automatically sealed and slow air loss is continuously prevented. This way, you can keep riding worry-free, even over dirt and sharp surfaces. The unique homogeneous composition prevents the sealant from accumulating in the tire. As a result, your bike continues to roll smoothly and stably without vibrations or imbalance. Moreover, the formula is non-toxic, does not dry out, and you don't need to shake the tire before use. Benefits at a glance: Self-sealing inner tube with Airlock sealant Continuous protection against flats and slow air loss Homogeneous sealant: no clumping or accumulation Non-toxic, durable formula Does not dry out Presta valve
Our standard Schrader inner tubes are made using a molding production method, which gives the butyl rubber a consistent thickness. This means no excess weight and a smooth, reliable ride every time. Each tube is individually vulcanized for consistent quality and optimal durability. Key features: Molded butyl rubber for consistent thickness Lightweight, no excess mass Smooth ride and reliable performance Individually vulcanized for optimal quality
