WIDER TREAD = GREATER PUNCTURE RESISTANCE We have added a wider tread to all of our Formula Pro Tubeless tires to better protect the casing and improve puncture resistance and durability. With better sidewall protection and improved handling, this tire looks forward to being ridden on cobblestones and gravel. RICE BRAN CERAMIC COMPOUND Formula Pro Tubeless X-guard is newly formulated with our high-grip compound, RBCC, to provide great grip and better wear life. X-GUARD: WORLD-CLASS PUNCTURE AND NICK PROTECTION The Formula Pro Tubeless X-Guard is constructed with a 40×40 TPI anti-puncture mesh, which covers the entire carcass from edge to edge. The X-Guard material was designed and optimized for its superior puncture protection qualities. We also used our new high-grip compound, RBCC, to combine incredible traction with longer wear life.
