Replacement Disc 2 For Nautilus/Bowflex 552 Dumbbells – Series 2, Improved Strength, Black Plastic

If you own a set of Nautilus or Bowflex 552 SelectTech dumbbells, you know how annoying it is when a part breaks.

This is a brand-new replacement for the Disc 2 (Series 2).

It's the black plastic weight plate that's part of the selector mechanism.

This one is actually an improved version with better strength, so it should hold up better than the original.

It's made for weight lifting, obviously, and it's unbranded but built to the right specs.

If one of your discs cracked or wore out, grab this and get your dumbbells back in action.

No more skipping that exercise because your equipment is broken.
