Last year, the Geax line of mountain bike tires was rolled into parent brand Vittoria. Most of the existing models carried over, and the Peyote, Barzo and Jafaki are the first three new treads to roll out under the Vittoria name.
The Jafaki is a moto-inspired tire with big knobs and even bigger side knobs to keep your firmly planted during high speed (read: descending) maneuvering. The widely spaced center section should clear quickly, making it a solid choice for enduro on anything but very dry hardpack.
The Barzo and Peyote skew more toward all purpose trail and XC use with lower profile knobs and faster rolling center sections. All three tires use sipes on the tread blocks to improve grip.
