Project 321 began as a company with limited offerings of high quality hubs manufactured in the USA to meet a niche market.  They combined their expertise in high precision CNC machining with innovative hubshell and gearbox designs to bring their latest line of hubs to market. 

The Project 321 ISO Disc front hub can be converted between a wide range of axle diameters, so no need to change your hub if you change your fork. Hub shells are polished prior to anodize and combined with CNC engraved logos to provide a brilliant finish. 

Hubs are fully serviceable with standard tools for many years of demanding use. All Project 321 hubs are 100% designed, manufactured and assembled in Bend Oregon and carry a 10-year warranty on hub shells.
