Three-spoke ultralight caster wheels feature a custom-made billet 6061-T6 aircraft grade aluminum hub that is machine-lathed for perfect balance. The proprietary, high rebound solid urethane tread is designed to minimize energy loss and absorb vibration. Sold by the Each.

The spherical, arched tread design improves pivotability for effortless turns and enhanced stability. The "virtual sphere" better distributes downward pressure allowing the wheel to maintain higher flotation and significantly reduces immersion into carpet, gravel, etc.

Designed exclusively for those of you who want the ultimate smooth ride. So much engineering went into a Frog Legs Soft-Roll wheel, it's no wonder no other caster wheel manufacturer offers a two-year warranty. They're so great you'll want a pair on every chair you own.

The Frog Legs Narrow Court Casters fits most 1" wide caster forks. Aluminum 3 spoke wheel available in 7 attractive colors. Black non marking tire and includes bearing.
