Rogue has spent the last 5 years and over $2,000,000 in scientific testing, research, and development to make our bars more durable than any other bars on the market. We have optimized our materials and manufacturing processes. We also developed a proprietary, patent-pending process we call Rogue Work Hardening (RWH™). Barbells treated with RWH™ are more resistant to the stresses of being repeatedly dropped. Rogue launched this project because of an unprecedented change in the manner in which barbells are used.
