Bontrager's AW3 Hard-Case tire offers armor-clad flat protection without sacrificing high-end road feel. Its triple protection reduces pinch flats, sidewall cuts and head-on punctures so you can concentrate on putting in the miles. And the Hard-Case's high-speed tread compound provides optimal traction and low-rolling resistance no matter what the weather, so this tire is equally at home racing or spring training. It even has a unique bead that closes the gap between the tire and rim for improved aerodynamics.
