Quick verdict
LiftEvidence editorial assessment
A 15 kg, 25 mm Olympic bar with needle-bearing sleeves, dual knurl marks, 150,000 PSI and a 1,000 lb rating. The thinner shaft suits smaller hands and the hook grip, and owners praise the free-spinning sleeves. Stock was low when checked, and the knurl is moderate rather than aggressive.
