This adjustable dumbbell assembly has a center weight of up to 90 lbs. There are attachable discs of
4 x 10 lbs
8 x 5 lbs
4 x 2.5 lbs
Please know that one of the two hexagon screws doesn't mount well, as you can see from the picture. But both end caps work fine. I set the price like a total price for selling the discs and the center core separately as is. The discs are all standard ones and can be used for other dumbbells. If you have good use for it, come take a look. Thanks.
