GBoost WBB RS WBB652RS
The GBoost World's Best Belt Race Series (WBB652RS) is the next evolution of GBoost's legendary World's Best Belt — engineered for riders who demand peak performance, maximum horsepower transfer, and unmatched durability under the most aggressive riding conditions. Where the original WBB set the standard, the Race Series raises it with a next-generation compound specifically developed to eliminate belt slip and put more power to the ground.
The RS compound is the defining upgrade — engineered using cutting-edge compound and cord technology to deliver better grip, stronger engagement, and more consistent power transfer no matter how hard you ride. Better shifting, longer belt life, and the confidence to push harder knowing your belt can keep up with everything you're throwing at it.
