Most tour balls are engineered around swings most golfers don't have. The Tour B RX is Bridgestone's answer: the same three-piece, urethane-covered Tour B construction as the X and XS, but tuned for swing speeds under 105mph — which covers the overwhelming majority of club golfers. You get real greenside spin and tour-ball feel without needing to compress a rock, and the 2026 refresh (the ball at the centre of Bridgestone's Open-week Leaderboard Edition kit) adds the brand's VeloSurge technology with a denser mantle for more ball speed and distance. Bridgestone's fitting logic is genuinely honest here: if you swing under 105mph, they point you at this rather than upselling you to the firmer X. The catch is the same as any premium ball — it only earns its price if your short game uses the spin and you don't lose three a round. If that's you, the RX is one of the smartest premium-ball matches in golf.
