Expand your NÜOBELL 550 Black to a complete 580 set
So what happens when 50 LB feels too little? Expand your existing 550 set to a complete 580 with up to 80 LB on each dumbbell. Comes with all the weights and the longer cradles fully assembled to convert your NÜOBELL 550 Black to a NÜOBELL 580 – for much less than you'd pay for a whole new set of 580.
Easy to make into a 550 again if you want to bring to the country house, the van or to the park training.
