Seismic: 75.5mm Alpha Longboard Skateboard Wheels

SEISMIC ALPHAS IN STOCK!

75.5mm tall x 62.5mm wide ALPHA Wheels
62.5mm running surface • Bearing seat offset 6% • Square outside edge, straight-cut inside edge
8.125 oz. each • Sold in sets of FOUR wheels

Available in two proprietary formulas –
BlackOps™: ultimate balance of speed and grip • extreme traction fresh • buttery and smooth broken-in • comfortable and predictable
Defcon™: Guinness WR speed • directional slide • long-lasting grip • slow, consistent wear

A giant step forward in race wheel engineering. The Alpha’s stout S-shaped edge profile optimizes lip support, maximizes traction under extreme G’s, and ensures predictable slide initiation and hookup. The running surface features a 0.5mm concave that pre-loads the edges, heightens rebound, and enhances in-slide feedback. The bearing seat is offset 6% for progressive lip engagement and more consistent wear.

The Alpha™ also marks the debut of Seismic’s proprietary Fusion™ core – at 46mm tall x 44mm wide, the largest and most supportive hub ever seen in a wheel this size. Features include a deep “saddle” profile, 8 perpendicular support beams (hollowed-out for lightness and aesthetics), and robust bearing lugs. The Fusion minimizes lateral wheel flex, supercharges edge support, and assures absolute mechanical lock with the urethane. Formed from 85D fiber-reinforced thermoplastic – the toughest hub material in the industry.

Mobo Note:  

Seismic Alpha is one of the newest race wheels currently on the market.  Featuring a HUGE core and extremely large lips this wheel is made for pushing the limits.

The resilient Defcon Formula will hold to the test of time while maintaing an extreme amount of performance, The super high rebound formula will have a tremendous amount of braking power on any type of pavement, allowing you to expand your comfort zone on the hill while continuing to have a reliable method of slowing down quickly in any situation.  The large core will support the high rebound urethane to create a wheel that will hold its shape no matter what you throw at it, meaning when drifting, the shape of the wheel is what will be slowing you down.  

The smoother sliding Black Op’s Formula is the perfect wheel if you aren’t looking for an extremely aggressive wheel but still want an incredible amount of roll speed and grip in any situation.  The smooth drifting Black Op’s urethane has a impressive amount of braking power as well, while drifting the Black Op’s formula digs into the pavement, and that is what is slowing you down.  Unlike the Defcon Formula the urethane lips of the Black Op’s wheels will wear but you will maintain the braking power throughout the entire life of the wheel because of how the urethane digs into the pavement.  You will also maintain a nice amount of roll speed throughout the life of the wheel due to the extra large core.

Both of these formulas are incredible and Seismic did an amazing job with these new wheels. If you are having a hard time deciding which formula to try out give us a call and we can talk about the type of skating you are looking to do and get our recommendations for the best formula for you!
