RitFit 4ft Olympic Bar has a bar shaft diameter of 25 mm, and a length of 1.2 meters (4 feet). Needle bearings allow for a smoother, quieter spin and a more reliable turnover at maximum loads. Built to the highest standard using high-quality steel materials, barbells feature an oxide finish and are built to be durable for a lifetime of quality weight lifting. These short barbells are mostly used for accessory work such as curl. The shorter barbell is suitable to perform close grip exercises with better balance. RitFit Olympic Bars provide 4ft/5ft/6ft/7ft length to choose from.
