I will admit that I am a sucker for unique and premium equipment.
In the world of strength training barbell clamps are the equivalent of the mousetrap. Everybody seems to agree that there has to be a better way.
I despise spring collars
Plastic collars never hold
I do like the OSO collars and have a couple of pairs
These collars are cool
Eleiko came out with the Open Collars
Screw down collars exist
Competition collars are out there as well
UPDATE 2/25/2022: I held off as long as I could, but finally broke down and ordered a pair of these.
UPDATE 3/3/2022: These arrived well packaged. I opened them to find a very nicely finished product. They weighed in at 461 grams and 462 grams. Within 1 gram of each other and less than 10 grams over the stated weight. But, they would not fit on my barbells which measured at:
Eleiko - 1.965 inches
Rogue Beater - 1.967 inches
Rogue Bella - 1.961 inches
They fit perfectly on my Rep Axle 1.945 inches
I will be getting a full refund, but hard to believe 2 hundreths of an inch make that much of a difference.
