2" Olympic Speedlock Vintage Collars

Thick, solid, extremely robustly built vintage iron collars. You could park a semi truck on top of these and they wouldn't bat an eye. Really quite substantially over engineered for the task they are meant to perform. Sadly, they are a very odd weight (a little over 2.5kg/~5.5lb each) and that makes adding them to your lifts a little bit of a headache, unless you are logging your workouts in kilograms; and if you're anything like me, you really abhor logging odd numbers for your weights. Adding 11.2 pounds to all of my sets really isn't something I'm going to do on a regular basis, so for the most part these sit on the vintage display wall and don't really get used. They cost between $100-$150 for a pair, so unless you're a vintage weights nerd like me, more modern clamp collars or spring collars make a lot more sense and cost a fraction of what these do.

They look great but they will not stay tight on deadlifts. I think the bolt could damage the sleeve on the barbell if you over tighten it.

These are fairly popular color that’s considered vintage and actually gets used in the gym regularly by lifters. I owned a pair for a few years before letting go of them, if I recall they had some weight to them and I personally never liked having heavy collars as it messed with my bar weight ocd.
