Each tube undergoes a stringent quality control process, including a 100% inflation test, to ensure it is free from defects. This meticulous manufacturing provides peace of mind on long tours, daily commutes, and demanding road cycling sessions, significantly reducing the risk of flats and keeping you on the road longer.* Versatile Performance with Presta Valve: Equipped with a 42 mm Presta valve, these inner tubes are ideal for a wide range of modern rims, including those used in road cycling and touring. The Presta valve provides a secure, high-pressure seal, is lighter than a Schrader valve, and is the standard for performance-oriented bikes. The 42 mm length offers excellent compatibility with shallow to mid-profile rims.* Seamless Construction for a Smoother Ride: Continental utilizes a seamless, mold-cured vulcanization process. This method ensures a perfectly uniform wall thickness and a consistently round tube, which eliminates weak spots, prevents premature failure, and contributes to a smoother, more stable ride quality.Main Features:* Engineered for touring, commuting, and general road use.* Seamless construction for enhanced reliability and ride smoothness.* Every single tube is individually inspected and tested for air retention.* Equipped with a secure and reliable 42 mm Presta valve.* Packaged as a 50-unit bulk box for workshop and high-volume use.Brand: ContinentalSpecifications:* Product Name: CONTINENTAL Tour Presta 42 mm 50 Units* Attributes: Inner tubes, Presta, Road Cycling* Valve Type: Presta (Sclaverand)* Valve Length: 42 mm* Model Code: CONTI TUBE TOUR WV, 28´´ 32/47-622/642 S42 ALL* 28-622 (28x1 1/8x1 3/4) * 32-622 (28x1 1/4x1 3/4) * 37-622 (28x1 3/8x1 5/8) * 40-622 (28x1.50) * 42-622 (28x1.60) * 47-622 (28x1.75) * 28-630 (27x1 1/8) * 32-630 (27x1 1/4) * 40-635 (28x1 1/2) * 44-635 (28x1.75x1 1/2)* CN
