Which NÜOBELL this is
The listing gives model and part number NB580BLA with the Black, 80 lb each pair variant selected, and its title calls it the Easy Twist 2024-25 Model. NÜO Athletics sells the NÜOBELL 580 Black, and the page's product data carries the SKU NB580BLA, matching the listing.
NÜO's page describes the 580 as sold as a pair, with a weight range of 5 to 80 lb per dumbbell. The user manual NÜO publishes covers four models, the NÜOBELL 220, 232, 550 and 580, so parts of it describe the family rather than the 580 alone.
This is the Black version. NÜO also sells a NÜOBELL 580 in silver under SKU NB580, which this site covers on a separate page; this page is for SKU NB580BLA only. The manual covers the NÜOBELL 580 by model name. The listing calls its store the only US source for genuine NÜOBELL parts, NÜO's page says spare parts are available, and the manual names NUO Athletic Innovation in Texas as the US reseller.
Weight range and how selection works
The listing and NÜO's page both give 5 lb increments from 5 to 80 lb, and the listing spells out all sixteen settings. NÜO's page says the pair replaces 16 pairs of traditional dumbbells.
Selection is by turning the handle while the dumbbell sits in its cradle, until the chosen weight is centred in an indicator window, according to the manual. NÜO's page calls this a patented twist-handle mechanism with a machined aluminium handle and a flat-head design.
The manual's usage page includes checks on the locking mechanism and warnings to read before lifting. Read the usage and safety pages in full before the first workout; we do not reproduce the steps here.
Materials and what arrives
The listing names powder-coated cast iron plates, knurled anodised aluminium handles and ABS and nylon polyamide components, and gives a handle diameter of 1.26 inches. NÜO's product page mentions the machined aluminium handle and flat-head design.
The manual's product overview labels the parts: a handle, stacks of regular weight plates with end plates and flat connectors, half plates, a wedge, an indicator window, and a cradle with inner and outer supports. We did not reproduce the manual's assembly steps.
The listing's table gives the item as 21.5 by 15.5 inches and 80 pounds. NÜO's page offers floor stands and expansion kits as separate products to combine with the pair.
Where and by whom it can be used
The manual describes the dumbbells as made for indoor home use and says not to use them outdoors or in wet locations. It states they are for ages 14 and up, that younger children should neither use nor be near them, and that teens up to 17 must be supervised.
For space, the manual asks for a clear workout area extending 24 inches (0.6 m) beyond the maximum reach of each exercise. It also says the cradle is where the dumbbells should rest when not in use.
The manual includes a consult-a-physician note and other exercise safety guidance. We do not repeat that guidance here; read the manual's safety pages before use.
Care and servicing
For cleaning, the manual says to use a cloth with warm water and mild soap and then wipe dry, and to avoid solvents, harsh detergents, chemicals and bleach. It says the dumbbells are lubricated and need no further treatment.
The manual asks for regular inspection and testing of the locking mechanism, and says damaged components must be replaced. It says not to let the dumbbells free fall or clash with each other.
The manual says repairs are to be done by certified retailers, and states that self-servicing the dumbbells voids warranty coverage. Spare parts are listed on NÜO's product page.
Warranty: 4 years or 2 years
NÜO's product page for the 580 Black shows a 4-year warranty. The user manual gives a 2-year warranty for residential use from the purchase date, and the listing's bullet also says 2 years.
Under the manual's terms, claims go to the store where you bought the dumbbells, with the original receipt and a photo or video of the problem. The customer pays shipping and handling for warranty replacements.
The manual excludes drop or slam damage, wear and cosmetic marks that do not affect use, damage from accidents, misuse, neglect or tampering, and use against its recommendations. Ask NÜO which term applies to a purchase made through this listing.
