Project 321 began as a company with limited offerings of high quality Lefty 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 Lefty front hub is compatible with Cannondale Lefty 1.0 and SL forks. 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.
