Extreme Durability: Polyurethane (CPU) is significantly more abrasion-resistant and tear-resistant than rubber or PVC. It is designed to withstand heavy daily use, repeated drops, and impact without cracking or chipping.
Odorless: Unlike many rubber products, CPU coatings are typically odorless, making them better suited for home gyms or enclosed spaces.
Floor Protection: The thick, shock-absorbent coating helps dampen noise when the dumbbells are set down and protects gym flooring from damage.
Professional Build: They usually feature a solid steel core for a consistent, compact size across different weights, and the handles are often made from high-quality, chrome-plated steel with knurling for a secure, non-slip grip.
