Overview
Rendpas sells the SP0355 as a matched 25 lb dumbbell pair in alloy steel, for 50 lbs combined, with a variant label noting five weights per side. Suited to home lifters filling a mid-range slot in a dumbbell rack.
The listing's color field describes a Pair-5 Weights build, which hints at a segmented or plate-loaded design rather than a single casting, though the data doesn't spell this out plainly enough to state with certainty.
- 25 lb pair, 50 lbs combined
- Alloy steel construction
- Variant labeled Pair-5 Weights
- Sold as a matched pair
Who it's for
Home gym owners who want a 25 lb pair for compound lifts like rows and presses. Not for anyone who specifically needs a confirmed single-cast, zero-assembly dumbbell, since that build detail isn't fully clear here.
Pros and cons
- 25 lb pair covers mid-range compound lifts
- Alloy steel build resists wear
- Sold as a matched pair, ready to lift
- Build detail, segmented vs single-cast, isn't fully clear from the listing
Performance notes
Alloy steel construction puts real load behind lifts like rows and presses, and the pair format means both hands get matched weight out of the box. The five weights variant note isn't detailed enough in the listing to confirm exactly how the head is assembled.
