Challenge Gravel Grinder Pneu pliable 700x42C TLR, noir (black)
Not road, not cyclocross - gravel races are in vogue and are attracting more and more participants. On long distances over unpaved roads, therefore, the Gravel Grinder feels particularly comfortable. And of course in everyday life, which requires a particularly insensitive tire.
TLR-Series Vulcanized Tubeless Ready with Nylon Superlight carcass
Vulcanized tires made of natural rubber score with a very good price-performance ratio and high durability at the expense of comfort and performance. Nylon is a carcass braid available in three main thread sizes - 33, 60 and 120 TPI (threads per inch) - and is wrapped around a wire bead or the aramid bead. The nylon braid is dipped in a bath of butyl rubber and then calendered (squeezed) between large steel rollers to produce the finished carcass. In bicycle tires, nylon offers a premium cost-benefit ratio due to its low price and comparative ease of processing.
Tubeless-Ready
Perfectly suited for use with tubeless systems: No tube, strong puncture protection and high efficiency.
Vulcanized synthetic rubber
To combine high durability with good riding characteristics, synthetic rubber is boiled and cured. The result is Challenge's Vulcanized Clinchers: easy running tires with high grip and good comfort at an affordable price.
