Challenge Latex 公路赛车 内胎 23/30-622 (700x23-30C) 法式 阀 (Sclaverand) 48mm

The ideal addition to your Challenge Handmade Clincher tire

Challenge manufactures the only seamless "one-piece" latex tubing on the market that offers a smooth, balanced ride without the wrinkles or bumps found in other tubing. Latex tubes are lighter, thinner and more flexible than butyl tubes, increase driving comfort, reduce rolling resistance and help to avoid punctures. The hose comes with a Presta valve with a removable core, making it compatible with both in-line and external valve extensions. By far the most affordable way to improve the performance and overall feel of your bike!
