Vittoria Peyote 29er Mountain Tire. Vittoria certainly has a renowned and enviable pedigree in the world of road tires, and their Peyote 29 mountain bike tire continues that legacy for cross country speed merchants who know only one tempo: all out. The low center tread will certainly inspire riders to push the pace, yet there's still enough bite on the edges to ensure you can carve your way through turns. A supple 120 TPI casing and folding bead help keep the weight to a minimum which makes all the difference in race situations or just spirited cross country sessions. You're not hallucinating the Vittoria Peyote is one seriously light and fast cross country option when speed is all you need.
