Easily swap out your tooth count or wheel type with our boardnamics press-fit pulleys. They're designed with an easy swap mechanism which lets you change out to gear differently or use a new wheel core.
This premium press-fit locks into the wheel core with a unique, tight fitting pin design.
Why Bearing pulleys?
Pulley runout or “wobble” on standard bolt-on pulleys hurt your drive system by constantly stretching and loosening the belt as the pulley rotates. The bolts have play and loosen overtime which causes the pulley to shift out of center under torque. The belt can skip more because of this. Pulleys with integrated bearings lock the pulley centered. Bearing pulleys also don’t have a retainer on the outside of the wheel for a more stealth look.
The ABEC pulleys fit most ABEC styles, including clone cores.
Entire pulley is CNC machined from 6061-T6 aluminum. Pins are stainless steel for extra durability where it counts. Adapters for Kegel/Labeda wheels and Flywheel/ABEC both available.
Available in 36 and 40 tooth counts. Being modular in design, changing tooth counts is simple and doesn’t require removing the entire pulley.
