Bells of Steel Adjustable Kettlebell

Averaged from + undefined
The verdict

The Bells of Steel Adjustable Kettlebell is the competition-style pick — IKFF-compliant 35 mm handle, steel shell, and 41 weight settings from 12 to 32 kg with 0.5 kg micro-loading. For lifters who are serious about kettlebell sport or who progress past the 40-lb ceiling that most adjustables top out at, this is the bell that scales with you. The trade-offs are price and adjustment speed; everything else is a clear upgrade over the budget tiers.

REP Fitness Adjustable Kettlebell
#1 · Top Score

REP Fitness Adjustable Kettlebell

Most refined feel of the picks here — beats the Bowflex SelectTech 840 and PowerBlock on swing dynamics due to the competition-style shape. Loses to the Bowflex SelectTech 840 on quick-change convenience and to the Yes4All on price. Single-range design means you may eventually want a second bell for a different weight bracket.

Bowflex SelectTech 840
#2

Bowflex SelectTech 840

Fastest adjustment mechanism in this round-up — beats the REP Fitness, PowerBlock, and Bells of Steel on dial speed. Plastic shell and 40 lb ceiling are the downsides versus the all-metal competitors. Loses to the REP Fitness on swing feel; wins on convenience and the included stand. Easier first-purchase than the Bells of Steel.

PowerBlock Adjustable Kettlebell
#4

PowerBlock Adjustable Kettlebell

Unique cowbell shape in this lineup — REP Fitness, Bowflex SelectTech 840, Bells of Steel, and Yes4All are all traditional round shapes. Magnetic pin adjustment is faster than the REP Fitness twist and the Yes4All disc system, slower than the Bowflex SelectTech 840 dial. Smaller weight range than the REP Fitness or Bells of Steel.

Yes4All Adjustable Kettlebell
#5

Yes4All Adjustable Kettlebell

Cheapest pick by far — significantly under the Bowflex SelectTech 840, PowerBlock, REP Fitness, and Bells of Steel. Cast iron build is a real advantage over the Bowflex SelectTech 840's plastic shell at this price. Loses to every other pick on adjustment speed and weight ceiling.
