The new Panaracer Race C Evo4 takes the improved suppleness and all round durability provided by our best-selling Race A model and enhanced the feeling on the road with the Classic File Tread pattern. The Race C Evo4s shape has been re-engineered to accommodate wider rim widths to continue to deliver superior grip and low rolling resistance. The file tread pattern gives an enhanced feeling of contact with the road, without compromising rolling resistance. Panaracer’s new ZSG Compound further reduces the low rolling resistance of the previous ZSG compound by 10%. In addition, grip in all weather conditions has been improved by 20% over the previous generation. We’ve further enhanced the ZSG compound by significantly increase the compound’s resistance to cuts out on the road.
