Project 321 G3 Rear Hub - 6-Lock, 32 Hole, 12x157mm

he Project 321 G3 Rear Hub is built for aggressive riders who demand instant power transfer, durability, and premium performance. Using the magnetically actuated M-Pulse pawl system paired with a 72-tooth drive ring, the G3 delivers an incredible 288 points of engagement (1.25°) — giving you near-instant pickup on tech climbs, rock rolls, and punchy trail features.

The 6-Lock rotor interface lets you run either 6-Bolt or Centerlock rotors, keeping your build flexible and future-proof. Wide bearing stance, optimized flange geometry, and a forged 7075-T6 shell combine for outstanding torsional stiffness and long-term reliability, even under heavy torque and DH abuse.

Choose the axle standard and driver you need — 142, 148 Boost, 157 SuperBoost, HG, XD, or MicroSpline — and pair it with your favourite rim for a bombproof wheelset that’s built to last. Available in P321’s signature anodized colour options for next-level customization.
