Bowflex Revolution SpiraFlex Resistance Plate Upgrade (Remanufactured)

The innovative SpiraFlex® technology enables you to achieve better, faster results by increasing the resistance of your Bowflex Revolution® Home Gym to 300 lbs (136 kg) (600 lbs. (272 kg) for leg press). Cutting-edge, non-metal plate technology looks like free weight plates but works independent of gravity to provide the resistance you need, without adding bulk, weight or noise to your machine. This easy to install upgrade just twists onto the Bowflex Revolution® in a snap.
