Project 321 Variable Sound 216 Engagement Hub
Project 321 had some really impressive hubs on display at Sea Otter this year. Their hubs offer a fantastic 216 point engagement with the use of a pretty nifty pawl system. By swapping out their loud or quiet pawls you’re even able to tune the sound to your liking from dead quiet to swarm-of-bees loud. Check out the great articles from MTBR and BikeRumor for plenty more details on these hubs that are made right here in the States.
