Vittoria e-Barzo Tire – 29 x 2.6 Tubeless Folding Black/Anthracite TNT G2.0. The e-Barzo is your choice for traction and range perfect for riding technical XC terrain with an e-bike. The magic starts in the center tread featuring an alternating ridge design and progressive sipe angles helps to keep this tire rollling fast. Cornering duties are handled by the moto-style block knobs laid out in a proven V-formation. The result is a tire that corners as fast as it rolls while still offering the protection of a full depth tread.
