Traction Wheels & Tread

VEXpro Traction Wheels are designed to be the ultimate in versatility and performance. These wheels include the VEXpro VersaKey mounting system, which ensures every sprocket, hub, and gear are perfectly piloted -- no more wobbly sprockets!

Wheels are manufactured from Glass-filled Nylon. Each Traction Wheel comes assembled in 1” wide configuration and also includes all hardware for 1.5” and 2” wide configurations.

Traction wheel assembly hardware is separate from sprocket mounting hardware. Sprockets are screwed into captive 8-32 standoffs. This allows for easy removal and replacement of sprockets without disassembling the entire wheel. No more worrying about your whole wheel falling apart just because you wanted to remove the sprocket.

Each traction wheel includes holes for use as bearing retainers.

Choose your Wheel and Tread below. Note that tread and traction tires are sold separately.
