The Race Type A EVO2 is the current evolution of the Race A tire and is clearly one of the best racing-training clinchers you can purchase. Improvements over the prior version include improved wear times and decreased rolling resistance. The inner diameter of the tire has been slightly increased for easier tire installation. Panaracer engineers made an already-great tire reach its full potential.
The Race A EVO2 is a product of innovative and proven technology that offers solid results on the road. It features the AC, All Contact shape and profile. This refers to the steeper angle and profile/shape of the tread from the center of the tire to the bead. In short, when the tire rolls over to a lean angle, you get complete contact or All Contact for superb grip and stability. It is very similar to Moto GP technology in the motorcycle world. This design works in tandem with Panaracer's ZSG dual compound tread. With ZSG, the center tread is a harder diameter for less resistance and faster rolling while the sides of the tire are a softer and more flexible compound for grip. Combine the dual compound ZSG tread with the AC profile and that's when the magic happens. Roll straight and fast, then lean the tire over for grip.
The ZSG tread is elastic and resilient which leads to longevity. We have found the wear times to be longer than many training tires. For added durability, Panaracer uses a protective layer which is coined the PT Shield. It is a flexible fabric that manages to be both superlight and pliant, similar to Kevlar, but stronger. The flexible PT Shield combined with the AX casing's fine threads provides the rider with a supple road feel with real world durability. Flats and cuts from road debris are not an issue with the Race A. Although billed as a race tire it is a perfect choice for either racing or training.
The Race A offers great technology and a tire that can compete with any high-end race tire in terms of both performance and durability. But when it comes to value and bang for the buck it remains in a class of its own. Try a pair and see what all the fuss is about.
