Smart weight lock works very well and very happy
Great product! Can recommend it confidently for everyone
Excellent and quality product. Moreover, it is cheap and value for money.
It moves easily under not-so-heavy weight. It has no specification on how much weight it can hold. I I have a dumbell with 5+2+1+1 KG plates and the clamp is too weak.
Brought these to save the effort of spin locks during lockdown home workouts These do not fit any of my 28mm standard bars at all. Fall straight off and even go onto the bar without opening/loosing the lock Wish i read the reviews beforehand.
So quick and easy to use - far easier than metal clamps
Does the job perfectly
I've been waiting for these to come in since march 2020 (non lockdown related but post part related). Always sold out. I've only just been able to order them successfully from this joke of a site. £3.50 but £5.99 for delivery?? is this a joke? not only that, parcel force 'attempted delivery' 3 days later (3 days when I spend this amount on delivery?? aye okay..) they didn't, I waited in for these all day. Not only that they said they'd posted a card through the door. again...lied. Frustrating when I really wanted these for my barbell. anyways, delivery prices is extortion and clearly using the lockdown BS for their profit
These have been excellent so far
Nice product but need a stronger grip. Ok up to rated weight but need a bigger brother
Stay away from these collars if you intend on lifting anything heavier than 6kgs! Would not recommend these at all as they are dangerous! I've had them come off the barbell mid set narrowly missing my head! I have had to stop using them and use 28mm spring clips instead. I dont have a problem with any other Decathelon equipment, but i'm really surprised that these collars can pass a health and safety tes to be sold by them
28mm collars that never fit my 28mm bar, so lose that they'd fall straight off without any weight on all, wish I read the reviews before purchase, hope i can take them back now theyve been opened
It says suitable up to 7kg per side of the dumbell, which isn't very useful. Doesn't scream quality when they only rate it for lighter weights. Better off buying spring collars
I wouldn't recommend these collars for anyone lifting anything but light weights. The loosen, the may slip and IMO they are dangerous. I've had one mishap and another near mishap with these. I don't know why Decathlon got rid of the old spin collars for this cheap rubbish, they make buying weights and bars from Decathlon not a good option any more.
