About the MX30 Rapid Change Adjustable Dumbbells

The MX30 Rapid Change Adjustable Dumbbells are a dial-style adjustable set that goes up to 80 lb total (40 lb per hand) in 2.5 lb steps, with a 1.25 lb plate size for micro-loading. The cradle and handset system lets you change weight fast, and the contoured antimicrobial grips are thicker than most at 1.4 in. At $199 at mxfitnesssupply.com as of November 3, 2026, this is the only new price listed, so there is no recent range to compare against. That is cheap for an 80 lb adjustable set, well under the $300-$400 typical of comparable dial dumbbells.

Pros
  • 80 lb total in one pair, up to 40 lb per hand
  • 2.5 lb increments with 1.25 lb plates for small jumps

Cons
  • Plastic and metal build, not all-steel like premium rivals

  • 9.5 in length at low weight grows bulky at the top end
  • Only one store lists it new, so price competition is thin
  • Cradle and feet add footprint versus a simple stand

Questions and answers

Is $199 a good price for the MX30?
Yes. An 80 lb adjustable pair at $199 undercuts most dial dumbbells in this weight class, which usually run $300 and up. It is the only new price listed as of November 3, 2026, so there is no lower recent price to wait for.
How much weight can each dumbbell hold?
The pair totals 80 lb, so each hand goes up to 40 lb. The 8.75 lb offset is the base handle and cradle weight you start from.
How small are the weight jumps?
You can move in 2.5 lb steps using the 1.25 lb plates. That is finer than most dial dumbbells, which jump 5 lb or more.
Are the grips too thick?
At 1.4 in (36 mm) they are thicker than typical dumbbell handles. Lifters with small hands may find them hard to wrap fully, especially at heavier loads.
What comes in the box?
The dumbbells, the MX patented handset cradle and the cradle feet. A weight rack is not included.
How do the MX30 compare with Bowflex or PowerBlock?
The MX30 is cheaper and offers smaller 2.5 lb increments. Bowflex and PowerBlock sets feel more solid and change weight with a dial or pin, but cost noticeably more at this weight.
