I was just in a shop to buy additional new Dumbbell Bars because I have many weights and do not always want to tweak with my Dumbbell Bars if I want to change the weight but rather just a dumbbell've ready. However, there were in the business only dumbbells with a larger diameter. That is why I would like to order me what the internet. The only problem is that I do not know to what diameter I should look now as I have not found 2.5 (Images of measurements in appendix). is 2.5 If properly measured, please send me a link to such a dumbbell bars.
