Modular 44 (D Bearing Hub)

Freshly Dirty

Regular price $75.00

The Modular 44 is Freshly Dirty's first yo-yo design with interchangeable rims. By using a standard hub-to-rim interface that is compatible with all Mod44 products from Freshly Dirty, one yoyo can suddenly take on many different forms. The Mod44 uses an O-ring system to keep the rim aligned and spinning smoothly, even after extended periods of regular wear and tear.

Generation 2 of the Mod44 includes restocks of the original C bearing hubs, as well as a new D bearing hub that is compatible with both new and old rims from the Mod44 collection.

Each yoyo includes 3 different sets of rims. With this hub, the included rims are:

One of the most exciting aspects of the Mod44 is open source rim design. Throughout the prototyping process, 3D printing was used to develop new designs and test them in real time. Freshly Dirty supports community members who wish to design and print their own rims. For more information as well as file downloads, click here.
