BlackOps Formula™: Fast and grippy, smooth slides once broken in.

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.

5/5

Premier bon point, les Alpha BlackOps ne sont pas des roues lourdes, le noyau a beau être gros, il reste léger et rigide. La roue prend pas mal de vitesse grâce à cela. Le freinage est puissant mais sans à-coups une fois la roue déglacée. Son programme est positionné sur du freeride bien rapide avec une accroche sûre, des freinages efficaces mais sans raccroche violente.Les riders plus aguerris et roulant plus dans le rouge du compteur préféreront le côté race de l'uréthane Defcon, où l'accroche puissante subsistera plus longtemps sur l'ensemble de sa durée de vie.Offertes par un ami qui les a choisies sur Fulkit, c'est un cadeau assez durable à se faire !! Service toujours au top by Pierre, what else
