Bells of Steel Competition Kettlebells are the pick for lifters who care about technique more than raw range. The product page says every bell from 4 kg to 48 kg has the same outside size, with the shell wall getting thicker as the weight goes up, so your rack position and clean stay put when you move up a size. Bells from 10 kg to 48 kg are held to +/-200 g, and the 4, 6 and 8 kg are held to +/-100 g. The 8 kg to 48 kg bells use a 35 mm handle and 60 mm window, and sizing follows Girevoy Sport Union, IKFF and IUKL specs. Each bell is gravity cast in one piece and carries a limited lifetime warranty. As of November 13, 2026, prices start at $49.99 for 4 kg and $109.99 for 16 kg, both sale prices. The catch is cost at the heavy end, with 32 kg at $206.99 and 48 kg at $489.99, and the line stops at 48 kg.
