Anyone who has muscled a bike into a corner at speed knows that having light wheels can make all the difference. The Slovenian company Rotobox (RBX) obviously agrees, and is producing these tasty carbon fiber wheels for most late-model sportbikes. By implementing a new way of joining the hub to the wheel, the end product better stands up to massive amounts of torque. While the radical look may appear chunky, a complete set weighs only a claimed 15-15.5 lbs. combined. Each spoke is hollow not only for weight savings but to allow more compressed air into each mounted tire—a feature that claims improved ride quality without sacrificing performance. With a design unlike any other wheel on the market, extreme weight savings and strength, RBX is a high-end option worth considering for any rider in the market for new rollers.
