York’s Pro Hex Dumbbell is an economy dumbbell with plenty of special features. The softened edges of the heads improve paint durability and adhesion by lessening the likelihood of cracking and chipping often experienced with the sharper edge hex heads.
The knurled handles are ergonomically contoured to fit comfortably in the users’ palm
Handles vary from 30 mm grip for increments through 20 lbs., increasing to a 35 mm grip for increments 25 lbs through 100 lbs
Handles are hydraulically pressed, creating a “fishtail” steel handle end
The handles are then permanently embedded in the heads by pouring molten iron around the fishtailed ends of a thick 35 mm solid steel shaft-improving the strength of the head / handle joint
