Building on Schwalbe's Racing Ralph tire, which is designed for speed and performance, the Racing Ray Addix Evolution 29in Tire features the profile we need for an aggressive XC counterpart. Shifted center blocks make for outstanding grip without compromising for speed, and stable shoulder blocks improve cornering traction. This design makes for precise steering and reliable grip, plus sporty handling. Top it all off with high braking performance in a range of conditions, and we've got ourselves a classic XC weapon.
