Reviews over the

Challenge Cross Grifo TLR

Good grip on dry and some wet mud and ice (inflated to 2.5bar). Were not sealing from the first few minutes, but after a few hours sealed well enough. Provides a nice cushioned ride for gravel and cyclox type tracks.

Pros & Cons

Pros & Cons

Went well on the rim(DT460) but difficult to get tubeless. Took several days anyway with constant re-inflating and refilling and shaking of sealant. After 1 week sealed enough to ride it. Tyre reasonable volume and 34mm wide. Can ride it at 2.5bar with 80kg weight without punching through roots and rocks. Lots of grip and steering stability, would buy it again. Points deduction for poor sealing, with Schwalbe X-One all-round I didn't have that problem, but then again it has less grip.

Pros & Cons

Good tyre, tested for use on dirt roads and in forests, decent performance on roads

Pros & Cons

Not going on my bike just yet but they were a bargain price so thought I’d get them before the price got bumped back up. The tyres themselves look well made and the sidewalls certainly look a lot thicker than the Vittoria terreno mix which I had on my bike last summer/autumn and was plagued with sidewall punctures.
