The Modular 44 is Freshly Dirty's first yo-yo design with interchangeable rims. By using one standard hub that is compatible with all 3 included sets of delrin rims, one yo-yo can truly act and feel like 3 entirely different designs. The Mod44 uses an O-ring system to keep the rim aligned and spinning smoothly, even after extended periods of regular wear and tear.

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.

C-bearing models come with Supersport Rims installed, D-Bearing models come with Tuner rims installed, and both versions come with extra Coupe & Cruiser rims in the packaging.
