This Challenge Gravel Almanzo Pro Open Tubular is really built for speed. The shallow profile gives you speed on the straight while the knobs on the side provide grip in the corners. The high TPI of the tire makes it very supple, which provides both grip in the corners and low rolling resistance. The tire is perfect for dry and hard terrain such as gravel due to its profile. Thanks to the Puncture Protection Strips you are well protected against punctures.
