Unfortunately, the high-price is an indication of the quality. For anyone that's spent a third of the price on competition-style weightlifting collars, will know from experience why they cost a third of the price. These are precision collars (we used them in a Guinness World Records lift!) and extremely well-made.
Features of the ATX Olympic Weightlifting Collars:
Made of steel with chrome finish.
Clamp and spin-lock mechanism.
Suitable for use with traditional olympic lifts.
Sold as a pair.
Weighs 5kg for the pair of collars (2.5kg each collar).
