Amazing product

This is really good product to use

Smart Disc Collar

Fantastic value. I use these to secure the weight plates on my power cage pulley system. Quick and easy to fit/remove

Great Purchase

Fits perfectly on the 28mm barbell as well as the dumbbell. Ease lock and unlock lever, which grips onto the bar and keeps weight plates in place. Great design and price.

Ok but not the best quality

I can't recommend these ones

Broke at 5kg, unsafe!

Just bought these, did some curls with 5kg plates each side (these seem to be rated to 15kg each side), so well under the limit. They were fine for a while, but after about 60 curls, one snapped, letting the weight crash against my table and bounce into my foot. Absolutely NOT SAFE!


These are brilliant and very sturdy!

Great concept/ design

First impressions were these are a cool design and after using them for the last few weeks I can now confirm these are a very cool design! Makes switching plates very easy and they lock really tight, much stronger than what I thought and they've not slacked off.

Ok in the horizontal, be carful in the vertical.

These are better than the older type and I was pleased with them until yesterday when I was using a dumbbell with 10kg (5 x 2Kg) weights either side making a total weight of 22Kg. I always check that the collars are on properly and had some confidence in that they are rated at 15Kg per side. After the second lift in the vertical, the lower weights just released without any warning and the collar was crushed into my expensive gym mat and tore it. Luckily I was fine but will only go for around 5Kg each side in the future for any work involving moving them into the vertical. Anything more and I will used the threaded collars.

Unique size not universal

Do not purpose if using for non decathlon product. The unique size on website doesn’t state it’s size. These are for 1.1inch bars not the standard 1inch bars. I’ve three sets of these that I cannot use because of this.

Corinthians clamps

Bought a set to use on my multiple dumbells and tricep bar. Doesn't fit, unless I am missing something they are simply to big when close and do not hold the weight.

Bar Collars Standard size

Prefer not to have smooth bar collars as they can come off and hazardous. However these collars provide a reasonbable hold, yet they are a bit delicate and prone to breaking. Good for quick release.
