Description
Made in Canada, with magnetic pawls and a 10 year axle warranty.
P321 G3 Hubs take all the best parts about the i9 Hydra and make meaningful improvements to reliability and durability.
- Magnetic pawls that reduce drag and eliminate wear and tear on leaf springs
- Innovative axle design that is backed with a 10 year warranty
- 1.25 degrees engagement, 288 POE
- Ring Drive with oversized teeth for reliability
- 6-lock technology that allows use of both 6-bolt and Center Lock rotors with zero compromise
We score them a 6.5/10 in loudness, and they are less high-pitched than a hydra.
Project 321 G3 is our strong recommendation for those looking for a high-engagement wheel set.
