I wanted to buy a standard diameter barbell bar. These were out of stock for quite a while due COVID, but eventually they came in. The Gym Direct website did not adequately describe the dimensions of these bars, but after two or three phone calls I was pretty satisfied I knew what to order so that the bar would fit the rack I had. Unfortunately, when it arrived, it did not fit. The centre part of the bar was too short. After further discussions, I realised that Gym Direct did not have a bar with a centre section greater than 100cm, and I needed 110cm. However, we worked out a way to do it by me buying a longer overall bar and an extra set of collars. They also agreed to pay freight both ways. Soon, the new bar arrived and it was good, but instead of two sets of collars, I got too sets of spring end locks. So now I am awaiting the second set of collars. Through all of this I have to say that Gym Direct were very cooperative. They need to improve their product descriptions, though. Also, I would have preferred a spin lock bar, but the only standard size one they sell has very peculiar dimensions, being short in the centre and very long at the ends. Arthur.
