I’ve got a pair of Olympic Dumbbells in my house, that I’ve just found in the garage, but unfortunately the collars/clamps have gone missing. I’m gonna buy some new ones, but I’ve no idea what size to get.
These are the ones I was going to buy, but as you can see they come in 4 different sizes - https://tinyurl.com/r8z6dpt
They come in 25mm, 28mm, 30mm, and 50mm. I’ve just measured my dumbbell handles, and they’re 6.5 inches (16cm) all the way around. But I still can’t figure out how this translates into millimetres.
Any help would be massively appreciated, as I need to order them ASAP to be here by tomorrow.
