Description The renowned Grand Prix has been updated with a new rubber compound and different traction pattern. Known for its extremely long wear, the Grand Prix is a staple training and racing tire for all cyclists, from weekend warriors to world champions alike. Folding or Wire bead. Black.
Poly X Breaker is a overlapping polyester fiber yielding a very dense fabric with minimal space between each individual thread making Poly X highly resistant to puncture without impeding the rolling resistance.
Black Chili delivers the ultimate combination of tire characteristics: the smaller particles yield more points of contact with the road surface (offering enhanced grip), are more tightly bound to each other (reducing wear), and the resultant structure is more flexible (lowering rolling resistance).
