ColdIronFitness is an authorized Trulap dealer.
Trulap makes twist-to-adjust dumbbells that replace a full rack of fixed weights. Choose the 8552 (8.5 to 52 lb) or the 8592 (8.5 to 92 lb), add a stationary or height-adjustable rack, or upgrade a 52 lb set to 92 lb later with the expansion kit.
Every Trulap set carries a 3-year warranty with one-time drop forgiveness, and ships free.
