The Rogue Kettlebell was designed around these requirements. Premium Material: We started with the highest quality first run iron ore available, not scrap. Void free surface: We use a proprietary casting process so each bell can reach the highest quality and have the cleanest finish possible. This also allows us to have a smooth, comfortable handle. Single Piece Casting: The Rogue Kettlebell is cast in one solid piece, creating a stronger, more reliable handle and a void free surface. The Rogue Kettlebell does not use plastic caps, plugs, or patches like lower quality products. Wide Flat Machined Base: We chose to machine the base of our kettlebell flat (not leave it as a raw casting) so it sits perfectly on the floor and does not wobble. Finish: The Rogue Kettlebell has a matte black powder coat finish that has a great feel and will hold chalk. This feels more natural than a thick epoxy finish. Colors: We color coded the handles. By associating each kettlebell weight increment with a different color handle, it becomes much easier for gym owners and trainers to direct athletes to specific kettlebells on sight alone. The 97 lb Rogue Kettlebell is all black without a colored handle.
