About Project 321 RG3 Hubs

Made in Canada, with magnetic pawls and a 10 year axle warranty.

Project 321 RG3 Hubs takes their proven, durable G3 platform with minor changes to better suit the road and gravel disciplines. 

• Magnetic pawls that reduce drag and eliminate wear and tear on leaf springs
• Innovative axle design that is backed with a 10 year warranty
• 2.5 degrees engagement, 144 POE
• Ring Drive with oversized teeth for reliability
• Optional 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 a little deeper pitched than the MTB G3. 

The Brig has sold over 200 sets of P321 hubs without a single warranty - they are very durable and we highly recommend them.
