Overview

The CAP SDRIS-025 is a single 25 pound hex dumbbell built from alloy steel with a rubber coating, meant to fill a gap in an existing set rather than serve as a matched pair.

With a piece count of one, this listing is for a single 25 pound dumbbell rather than a pair or a set, so plan to buy two if a matched pair is what you need for most exercises. The rubber coating over an alloy steel core is a common combination meant to protect floors and reduce noise compared to bare iron.

  • 25 pound weight
  • Hex shaped head
  • Rubber coated alloy steel
  • Sold as a single unit

Who it's for

Lifters who need to add or replace a single 25 pound dumbbell in an existing set. Not a full pair for someone starting from scratch.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Hex shape prevents rolling on the floor
  • Rubber coating protects floors and reduces noise
  • 25 pound weight fits mid range strength work
What to check first
  • Sold as a single dumbbell, not a pair
  • Fixed weight cannot be adjusted

Performance notes

The hex shape keeps the dumbbell from rolling on the floor, and the rubber coating over the steel core cuts down on noise and floor damage compared to uncoated iron. Sold as a single 25 pound unit, so buy two if a matched pair is what you need.
