Wheels SEISMIC Alpha 75.5mm 77A Blue BlackOps

The Seismic Alpha 75.5mm 77A Blue BlackOps Wheels are designed for riders who need maximum traction and control on rough or inconsistent pavement. Their 75.5mm diameter and 62.5mm width offer momentum for straightaways while maintaining agility for technical racing, pre-drifts, and tight corners. The 62mm running surface ensures consistent wear, excellent grip, and smooth handling even in extreme downhill conditions. Made with Seismic’s BlackOps™ urethane, these wheels provide a comfortable and predictable slide with an outstanding balance of speed and grip. The 77A Blue durometer is optimized for sticky and controlled "in-the-pavement" slides, making them perfect for rough and inconsistent surfaces where extra traction is needed. Built around Seismic’s Fusion™ core, the largest and most supportive hub ever used in a wheel of this size, these wheels deliver enhanced edge support, absolute mechanical lock with the urethane, and superior rebound. The bearing seat, offset by 6.5%, ensures progressive lip engagement and uniform wear, while the square outside edge and straight-cut inside edge maximize grip and stability under extreme G-forces.
