Bridgestone Tour B X Golf Balls. Maximum Distance For Fast Swing Speeds. Bridgestone have reinvented the Tour B X to feature new REACTIV iQ cover technology. Until now you had to choose more distance or more spin. With REACTIV iQ you can now get more distance and more spin out of the same golf ball. Designed to fit golfers with tour fast swing speeds of over 105mph, the new Tour B X has higher ball speed for maximum distance while having 'hit and sit' performance on approach shots. Consistent flight and performance in the Tour B balls are a result of the proprietary Seamless Cover Technology. Validated professionally by Bryson DeChambeau and Matt Kuchar.
