Bowflex Select-tech 552 Dumbbells series 2 replacement discs. Disc #5. Discs are 3D printed to scale. 

Since they are 3D printed, there may be minor imperfections or blemishes. Printed with strong, durable, high quality PLA+. Tested to fit and function as original discs, as well as for normal everyday use, but if you drop your dumbbells, they may crack similar to original Bowflex discs. I've replaced multiple original discs on my set of dumbbells and these replacements work great and I've yet to break one. See photos for disc configuration, just in case you don't know which disc you require. There are plenty of videos online that can help you with taking apart your dumbbell to replace the disc. 

**Note: Prior to ordering, please make sure to know which series of dumbbells you have. Series 2 typically has the RED bar across the weights and says Bowflex on the bar, as well has white numbers on the dial (set with grey bar and a dial with orange or red numbers is series 1 and these discs will not work for series 1). If you still happen to order the wrong disc, I will exchange but will have to charge shipping costs to send exchange back to you. If you are not sure which type you require, please contact us and we'll assist you. Cost is for materials, printer wear and labor only. We do not charge for the design.
