The MX55 Selectorized Dumbbells features the unique MX SELECT patented rack and pinion system; compact size, balanced and secure.

The MX55 Selectorized Dumbbell set on its sleek rack (rack included) is space efficient and easy to use, perfect for any in-home fitness room. One pair of MX55 Dumbbells replaces a 10-piece dumbbell set and a cumbersome rack.

The selected weight is locked into place as soon as the selector dial is pushed home. Safe, convenient, accurate and space efficient, the MX55 Selectorized Dumbbell System is a perfect addition to any home workout area.
