Challenge GRAVEL STRADA BIANCA {TLR} (PLIANTS) NOIR/MARRON 40-622

The Challenge Strada Bianca Race TLR is a gravel tyre built for riders who tackle both paved roads and unpaved tracks. In a 700x40C size (ETRTO 40-622), it sits in a sweet spot between speed on tarmac and comfort on rougher terrain.

The Tubeless Ready (TLR) design means you can run pressures as low as 1.7 bar (25 PSI) without risking pinch flats. At lower pressure, the tyre conforms better to the ground, improving traction and cushioning on gravel, cobblestones, or dirt paths. Simply pair it with tubeless rim tape and sealant — no inner tube required.

The 120 TPI nylon casing is noticeably supple. More threads per inch means a thinner, more flexible structure that absorbs trail chatter and reduces fatigue in your hands and arms over long rides. The Race vulcanised construction bonds the tread firmly to the casing for lasting durability.

The aramid/kevlar foldable bead makes this tyre easy to roll up and stash in a jersey pocket or bag for emergencies. The classic black/brown colourway fits naturally into the gravel aesthetic without looking out of place on a refined build.
