Frequently Asked Questions
Do these hex dumbbells come in pairs?
Most CAP Barbell hex listings are sold individually — check the product description carefully. If you need a matched pair for exercises like dumbbell presses, purchase two of the same listing or look for a pair-specific product.
How can I reduce the 'new dumbbell' smell?
Air the weights in a ventilated area for 24–72 hours and wipe them with a mild soap solution. Baked enamel finishes usually off-gas less; persistent strong chemical odors may fade after several days.
Are coated heads better than bare cast iron?
Coated heads protect flooring, reduce noise, and can limit rust — good for home gyms. Bare cast iron offers a classic feel and sometimes better longevity, but may chip and show wear unless finished with baked enamel. Choose based on whether floor protection and odor are priorities.
