Best comp kettlebells for home gyms in 2026

What is a comp kettlebell?

A comp (competition) kettlebell keeps the same handle thickness, bell diameter and bell height at every weight, instead of growing the bell as weight increases like standard cast-iron bells do. PRx states its competition kettlebells “come with the same size handle, bell diameter, and bell height” across 16, 24 and 32 kg, which is the defining trait buyers searching “comp kettlebell” are usually after.

That consistency matters for cleans, snatches and rack position work, where a bigger bell at heavier weights can change wrist angle and forearm contact. Bells of Steel calls this “true competition sizing” on its adjustable model, pairing it with 0.5 kg micro-loading so lifters can add small jumps instead of the 4–8 kg leaps common on cast-iron sets.

How we ranked these comp kettlebells

Picks are ordered by four factors pulled only from each maker’s published page: fit for true comp sizing (consistent dimensions across weights), build details (cast method, handle spec, locking system), price per kilogram at listed weights, and range of weights or bundle options. No product was physically tested; rankings come from maker specs and prices only. See /how-we-research/ for the full method.

Where a maker didn’t list a spec — handle diameter, warranty length, or exact tolerance — that gap is called out under “skip” rather than filled in with a guess. Prices shown are snapshots from each brand’s site on the date checked and will move.

Comp kettlebell price and weight comparison

Brand	Weight range shown	Fixed-weight price range	Adjustable price (if listed)
Bells of Steel	4–48 kg (fixed line), 12–32 kg (adjustable)	$57.99–$126.99 (4–14 kg shown)	$220.99–$598.99
PRx Performance	16–32 kg	$109.99–$189.99	Not offered
Mikolo	16–32 kg	$109.99–$199.99	Not offered
XMark	8–32 kg	$92.00–$169.00 (12–28 kg shown)	Not offered
Titan Fitness	20–32 kg (fixed), 12–32 kg (adjustable)	$149.99–$174.97	$212.97

Titan’s adjustable model is the cheapest way into a 12–32 kg comp-style range in this comparison, while Bells of Steel’s adjustable bell asks more but adds a 0.5 kg increment and a steel lock instead of a simpler mechanism.

Which comp kettlebell costs less per kilogram?

Dividing price by weight shows where the value gaps sit at the top end of each lineup (our calculation, based on sheet prices):

Brand & weight	Price	Cost per kg (our calculation)
Bells of Steel, 14 kg	$126.99	~$9.07/kg
PRx, 32 kg	$189.99	~$5.94/kg
Mikolo, 32 kg	$199.99	~$6.25/kg
XMark, 28 kg	$169.00	~$6.04/kg
Titan, 32 kg	$174.97	~$5.47/kg

Titan’s fixed 32 kg bell has the lowest cost per kilogram in this set, with PRx and XMark close behind. Bells of Steel’s small 14 kg bell costs more per kilogram, which is normal for lighter comp bells since handle and casting costs don’t scale down with weight.

Bells of Steel Competition Kettlebells — best for a full weight ladder

Best for: lifters who want one brand’s bells to feel identical from 4 kg to 48 kg. Bells of Steel casts these in one gravity-cast piece with a hollow core, so there’s no seam and no filler weight added to hit a target number. The line spans 16 sizes and carries a 4.9-star rating built on buyers who say they replaced mismatched cast-iron bells and moved up the ladder without a sizing change. Sheet pricing only runs from $57.99 (4 kg) to $126.99 (14 kg), so confirm current pricing on heavier bells directly with Bells of Steel.

Bells of Steel Adjustable Competition Kettlebell — best for small spaces

Best for: apartments, garages or any space where a full rack of bells won’t fit. One shell covers 12–32 kg across 41 settings with 0.5 kg jumps, held in place by a steel-on-steel lock instead of plastic clips. Bells of Steel says the design “essentially expands the product downward” with an optional plastic bottom add-on, stretching the usable range to 9–32 kg. Singles start at $220.99 for the 12–20.5 kg version and $332.99 for the full 12–32 kg version; pairs save 10%.

PRx Competition Kettlebells — best single-weight value

Best for: lifters who know their target weights and don’t need a bundle discount. PRx’s 16, 24 and 32 kg bells share handle diameter, bell diameter and bell height, so grip and rack feel stay the same as weight goes up. Pricing runs $109.99 to $189.99 across the three sizes, undercutting Mikolo’s matching weights by a few dollars at each step.

PRx Competition Kettlebell Bundle — best two-bell starter set

Best for: buyers who want two comp weights in one order rather than tracking two separate checkouts. Bundles mix any two of PRx’s 16, 24 and 32 kg bells, priced $259.99 to $379.99 depending on the pairing, and share the same 12 in x 9 in x 6 in footprint as the single bells. A 16/16 kg bundle at $259.99 works for households training two people at the same weight.

Mikolo Kettlebell Competition KB5 — best with a matching rack

Best for: buyers who want storage solved in the same order as the bells. Mikolo prices singles at $109.99 to $199.99 across 16, 24 and 32 kg, sells a dedicated rack for $119.99, or bundles three pairs (16/24/32 kg) with a rack for $999.99. That set price is a large step up from buying six singles plus the rack separately, so check the math against your exact weight needs before choosing the bundle.

XMark Competition Kettlebells — best budget weight range

Best for: lifters building a ladder gradually from lighter starting weights. XMark lists prices from 8 kg (currently unavailable) through 28 kg on our product research, with a 12 kg single at $92.00 and a 28 kg single at $169.00. Sets are available for buyers who want multiple weights discounted together rather than adding singles one at a time.

Titan Fitness Competition Kettlebells — best low-cost fixed weights

Best for: budget-focused buyers who only need two fixed weights or a lower-cost adjustable option. Titan’s 20 kg bell runs $149.99 and its 32 kg bell runs $174.97, both cheaper per kilogram than most comparable weights from other brands in our product research. Its 12–32 kg adjustable kettlebell at $212.97 is also the least expensive adjustable comp-style bell in this comparison, though Titan’s page doesn’t list an increment size the way Bells of Steel does.

Comp kettlebell vs. adjustable kettlebell: which fits your space?

Fixed comp bells (Bells of Steel, PRx, Mikolo, XMark, Titan singles) suit lifters who train at set weights for cleans, snatches and swings and want the exact same bell feel every session. Adjustable comp bells (Bells of Steel’s 41-setting model, Titan’s 12–32 kg bell) suit smaller spaces or lifters who want fine 0.5 kg progression without buying a full rack. For a deeper look at adjustable-only options outside the comp category, see /adjustable-kettlebell/; for standard cast-iron bells, see /cast-iron-kettlebell/.

How do comp kettlebells compare to dumbbells for the same movements?

Kettlebells and dumbbells train overlapping muscle groups but differ in how load moves through swings, cleans and carries — that comparison is covered in full at /kettlebell-vs-dumbbell/. If you’re deciding between a kettlebell ladder and an adjustable dumbbell set for a small home gym, /are-adjustable-dumbbells-worth-it/ and /best-adjustable-dumbbells-with-stand/ walk through the dumbbell side of that decision using the same maker-spec approach.

How much rack space does a comp kettlebell ladder need?

REP Fitness sells dedicated kettlebell storage separate from any bell maker in our product research: a 41-inch Dumbbell & Kettlebell Shelf at $179.99, an 82-inch version at $329.99, and modular components including a KB Flat Shelf single at $130.00. A five-bell ladder (say, Bells of Steel’s 4, 6, 8, 10 and 12 kg) likely fits the 41-inch shelf, while a full 16-weight ladder up to 48 kg needs the 82-inch option or multiple modular shelves. Store bells on a stable rack rather than stacking them loose on the floor, especially on hard surfaces — a padded surface like those covered in /best-gym-flooring/ also protects both the bell and the floor if one gets set down hard.

Bottom line

For a true comp weight ladder with consistent one-piece construction, the Bells of Steel Competition Kettlebells lead on build and rating, while its Adjustable Competition Kettlebell is the pick for small spaces needing 12–32 kg in one shell. Budget-focused buyers get the lowest per-kilogram fixed weights from Titan Fitness, and PRx offers the most consistent single-to-bundle pricing if two weights are the goal from day one. Compare current prices directly with each maker before buying, since every figure here can change.
