Piper G14 M-DISC 125mm – Premium Marathon Wheels

★★★★½ 4.7 out of 5 — based on 327 reviews

The Piper G14 M-DISC is arguably the fastest marathon wheel in the world. The successor to the legendary Matter G13, made in the USA by Piper with the original Insane-a-Thane urethane formula known for its unique combination of grip and speed.

The M-DISC technology displaces weight to the outside of the wheel via an 89mm disc core, creating greater moment of inertia and longer-lasting rolling momentum. The Dual Durometer Banded construction combines a soft inner band (67A, “supercharged band”) with a harder outer layer for grip and speed in one.

  • M-DISC technology – disc core displaces weight outward for longer momentum
  • Insane-a-Thane urethane – original formula, unique grip + speed combo
  • Dual Durometer Banded – soft inner band (67A) + hard outer layer
  • One-piece bearing seats – precision tooled for consistent performance
  • Made in the USA – premium American craftsmanship

Upgraded from regular 125mm wheels. The M-DISC momentum is noticeable — you just keep rolling. Amazing marathon wheel!

★★★★★ Ben N. — 2026-01-05

The successor to the G13 and it lives up to the legend. Fastest 125mm wheel I’ve ever ridden. The Dual Durometer is genius.

★★★★★ Michael H. — 2026-02-19

Nothing comes close to the Piper M-DISC. The Insane-a-Thane urethane is magical — grip in corners, speed on straights. Worth every penny.
