CHALLENGE Almanzo Pro Tubular 700C x 33 gravel tyre

The Almanzo is the ideal tire for gravel and adventure riders seeking more control than the Strada Bianca and lower resistance than the Gravel Grinder. Open Tubular tires use the same construction and materials as Challenge Tubular tires. But instead of stitching the casing into a closed tubular tire, the sidewalls are folded into a bead using aramid fibers. This open design offers the advantages of a tubular tire, but can be mounted like a normal clincher tire.
