Tufo Flexus Primus Cyclocross Tire

The Tufo Flexus Primas Tubular is a fantastic choice for an all-around cyclocross tubular. The close-spaced knobs provide both aggressive traction and low rolling resistance. There in enough space between the knobs so they can shed mud reasonably well.

The new Si 363 tread compound lowers rolling resistance by 10%. It also offers better grip in wet conditions as well as higher durability and smoother ride. A new casing with long aramid fibers increases puncture resistance and lessens vibration transmit ion for improved comfort.
