Gym Equipment Specifications and First-Use Notes
Every product page has a specification table. This article collects the figures customers ask about most, and the notes that apply before first use. Prices and stock are always on the product page.
Notes that apply across the range
-
Dumbbells and plates are sold in pairs unless the listing is a set. A listing such as "10kg x 2 (20kg)" is two dumbbells or two plates.
-
Rubber hex dumbbells are coated with a silicone oil that protects the rubber in transit. Wipe them down with a dry cloth before first use. This is normal and is not a defect.
-
Weight tolerance: ±3% on hex dumbbells and tri-grip plates, ±2% on bumper plates, cast iron plates and kettlebells.
-
Assembly tools are not included with dumbbell and kettlebell racks. The racks need 17mm tools; our 17mm Spanner Set (two spanners, non-returnable) is the minimum needed.
-
All our plates and bars are Olympic 50mm (2 inch). Standard 1 inch plates and bars are not compatible.
-
Warranty: one year on equipment unless the product page says otherwise. Concept2 machines carry a two-year parts guarantee. See Product Warranty.
