Made from premium low odor rubber, our dumbbells are a classic rubber coated hex design that is quiet and easy on your floors. Special care was taken to select a rubber formula without the harsh chemical smell found in many rubber hex dumbbells. The chrome plated handle is straight and fully knurled for maximum grip. Unlike slippery "ergonomic" handles that only have knurl across part of the handle surface, our full knurl gives you a secure grip on the dumbbell at any weight.
Handle diameter is 28 mm at 5 to 15 lb weight, and 34 mm at 20 lb and above. The thicker 34 mm handle adds comfort on heavier weights.
Dumbbells heads are securely attached via press fitting and welding.
