XS Sports 25mm / 1" Spring Weight Clamp Collars Clips Barbell Dumbbell Quick Release

Honestly, amazing. I cannot recommend this enough for any beginner or other who is using spin-lock at the moment. I had a spin-lock and my routine was a lot slower due to the time I had to spend undoing the locks. These locks actually hold the weights in better than the spin-locks which used to undo themselves as I went through my sets. They're so easy to use and all around just a great product. I've only had them for about two weeks but they seem extremely robust and are well worth the low cost.

Lovely little item, saves a lot of time when you have twist lock weights.

I bought this to stop my waits for falling off my dumbbell. The clips that came with the dumbbells kept unscrewing and falling off. However since getting these new clips my weight have stayed secured the whole time. They are a great price for what you're getting and they do the job.

I ordered two packs of these and out of the four one was faulty and was totally loose when put on bar. I contacted XS sports and they sent me another two packs. So three extra - top marks to them for that. The Spring clamps themselves are not great. On the second two packs I received one of them had the opposite problem to the first lot in that it was too tight to go on the bar. However, the rest are ok and I have ended up with a spare. The clamps will not hold the weights in place as tightly as the thread on collars and the weights will rattle on the bar slightly -but stay on securely. How long they will stay effective for only time and use will tell but it's worth trying at the price and if you get a dud then XS will send a replacement.

Didn't fit the bar, waste of money. I threw them in the bucket.

I bought these as my local body pump classes, the clamps were difficult to fit the bars and was a battle to find a pair that fit. These have taken the stress away as they fit easily on all the different type bars provided. I could not be happier and at a good price too.

1 inch clamps, they work perfect with my 1 inch dumbbells. Don’t be a wimp just squeeze them and put them on the bars.

Very good product that arrived well before the due delivery date. The clips grip the barbell firmly so that there is no danger of slippage. For the price and service this product is highly recommended.
