MPC Enigma – X-Firm (90mm / 100mm / 110mm)
Enigma X-Firm is part of MPC’s most advanced wheel line ever created — a complete reengineering of hub design, urethane formulation, and long-distance durability. Designed under the same strict standards that made MPC a world leader, Enigma X-Firm delivers unmatched consistency, roll, and stability for elite track and road racing.
This wheel was built to solve one challenge: maximum roll without sacrificing grip. MPC’s updated turbine hub and refined natural urethane create a wheel that grips confidently in corners yet holds exceptional top-end speed on straightaways. In MPC lab and field testing, Enigma showed a 25% improvement in wear life compared to competing wheels — all without losing the signature MPC snap and rebound skaters expect.
