Vittoria Syerra 29" Tire A cross-country tread profile with trail-rated grip and protection, the Vittoria Syerra 29" Tire is an excellent choice for down-country riding in mixed terrains. Nimble and lightweight, yet still aggressive, the Syerra Tire offers a balanced tread profile, complete with angled center knobs, small transition knobs and large cornering blocks. Siping on all knobs help to add grip and traction and the spaced-out design helps to shed mud. Vittoria used their Graphene rubber compound which incorporates four different rubber compounds for the best balance of grip, speed and durability. For protection an Anti-Pinch Flat sidewall insert was added to help protect the sidewall from punctures. This tire is tubeless ready and features Vittoria Tubless TLR casing for a lightweight and supple casing.
