Ready to transform your ride? Meet the Radium Performance SR125 wheels – the game-changing hybrid that’s redefining what’s possible on four wheels. These aren’t your typical skateboard wheels; they’re engineered marvels that deliver the precise road feedback of urethane with the plush comfort of pneumatics.
What makes the SR125s special? Picture this: you’re carving through tight corners at low speeds, then seamlessly transitioning to buttery-smooth stability at 45mph. The secret lies in their offset core design and high-grip NR/SBR rubber compound that grips like pneumatics but handles like a race car.
The innovation doesn’t stop there. Traditional skate bearings couldn’t handle this level of grip, so Radium developed their revolutionary Core system supporting 28mm mountain board bearings. This means compatibility with 8, 10, and 12mm axles – talk about versatility! The 12-hole pattern features four threaded holes for direct pulley mounting, eliminating support bearings and those frustrating shim washers.
At 125x75mm with compression holes for off-road comfort, each 770g wheel is built around a robust 6061-T6 aluminum core. Whether you’re a DIY enthusiast or seasoned rider, these wheels promise to elevate your electric skateboarding experience. Just remember – bearings sold separately, but the performance? Absolutely included.
