TriForm 3-in-1 Adjustable Weight Set vs CAP 110lb Elite Olympic Grip Plate Set

Buy the TriForm if you want one compact set that becomes a dumbbell, barbell and kettlebell for home training in a small space. Buy the CAP 110lb set if you already own a 2-inch Olympic bar and want durable cast iron plates with grip holes. The TriForm is more versatile but its moving parts and dial mechanism are the weak point over years of use. The CAP plates are simple, near-indestructible cast iron, but they are plates only, not a full system.

  • Choose the TriForm 3-in-1 System if you train in a small space and want dumbbell, barbell and kettlebell work from one adjustable set without buying a separate bar.
  • Choose the CAP 110lb Elite set if you already have a 2-inch Olympic bar and want solid cast iron plates with grip holes for loaded carries and floor work.

Prices

  • TriForm 3-in-1 Adjustable Weight Set: $99.99 at Walmart (last seen Nov 10)
  • CAP 110lb Elite Olympic Grip Plate Set: $48.99 at Walmart (last seen Nov 10)
  • Difference: the CAP 110lb Elite Olympic Grip Plate Set is $51.00 cheaper than the TriForm 3-in-1 Adjustable Weight Set at the latest prices (Nov 10)

What reviewers say

TriForm 3-in-1 Adjustable Weight Set

  • 4.6 / 5114 ratings

Rated 4.6 out of 5 from 114 ratings, owners like the space saved and the fast weight changes. Most criticism centers on the 45 lb ceiling and the bulk of the adjustable dumbbell.

What people mention
  • VersatilityPraisedOwners like getting dumbbell, barbell and kettlebell work from one set.
  • Weight changesPraisedThe dial lets people change load quickly between sets.
  • FootprintPraisedIt takes far less room than separate fixed weights.
  • Max weightCriticisedThe 45 lb limit is too low for heavy lifts, reviewers say.

CAP 110lb Elite Olympic Grip Plate Set

Owners of CAP's cast iron grip plates describe accurate weights and a useful three-hole grip, with the set working well for warm-ups and lighter lifts. Complaints center on rough casting, paint chipping around the holes and the lack of heavier plates in the set.

What people mention
  • Grip holesPraisedOwners like the three-hole design for carrying plates and sliding them onto the bar.
  • Casting finishMixedSome plates arrive with rough edges or flash that needs filing, while others are clean.
  • Paint wearCriticisedPaint chips around the grip holes and where plates meet the bar.
  • Weight accuracyPraisedBuyers report the plates weigh close to their stamped values.

Questions and answers

Which is better for a small apartment gym?
The TriForm. It replaces a dumbbell rack, a barbell and a kettlebell with one compact set and changes weight in seconds. The CAP plates still need a bar and floor space to load.
Which lasts longer?
The CAP plates. Cast iron with an enamel finish has no moving parts and holds up for decades. The TriForm's dial mechanism is the part most likely to wear or jam.
Is the TriForm worth stepping up to over loose plates?
If versatility and speed matter more than maximum load, yes. It gives you three tools in one. If you already own an Olympic bar and want heavy loading, the CAP plates are the better fit.
Can I use the CAP plates without a bar?
Yes. The 3-hole grip design lets you hold plates directly for carries, presses and core work. You just can't do barbell lifts without a 2-inch bar.
How much weight can the TriForm handle?
It adjusts from 20 to 45 lb. That suits light to moderate training but is low for heavy squats or deadlifts, where the CAP set's 110 lb total goes further with a bar.
Do the CAP plates fit standard bars?
Yes. The 2-inch center hole fits standard Olympic sleeves. The TriForm uses its own handles and bar sections, so its plates don't swap onto an Olympic bar.
