Replacement wrench for the Chin-Sprint wheel or Treadmill Wheel (14 inch).
Maintenance: Wheels have a center bearing cartridge that is subject to wear-and-tear over time with continuous use, but this replacement will make any old wheel work like new! Some customers go years without replacing it, while others may have to replace it once or twice per year. Product warranty is 60 days, where Exotic Nutrition will provide a complimentary replacement center bearing cartridge.
