The Tufo Flexus Cubus tubular features large, aggressive square knobs for maximum traction. The Cubus is a excellent choice for all conditions and is particularly at home in the most difficult terrain. The generous spacing between the knobs allows it to shed mud extremely well. Even with the Cubus's aggressive tread, it still has low rolling resistance and can be used in dry conditions and hard pack.
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.
