The standard 5' bar was too narrow for me to safely use with squat stands so I went searching for a new one suitable for my standard York weights. Amazon had the best prices at the time and the choice was between a 6' bar and this 6'6" spin lock beefy bar.
I decided on the larger bar, as the distance between the inner collars was greatest. I chose my squat stands, Bodymax CF310, as they had adjustable height and adjustable spotter catchers and this meant that with a longer bar I would be able to use the set-up to self-spot for bench, incline and shoulder press when used with my basic York bench.
The bar arrived very quickly even though I chose super saver, and it was very well packaged. At the time the Royal Mail was still having problems, but Amazon had used a different service.
The distance between the collars is 4' and there is 15" for weights either side. (5' bar: 3'1" between collars and 11" either side.) I think the beefy refers to it being a slightly wider grip bar which is good, but I've found the highs of the threaded ends are actually a little lower than the standard bar by a mm or two. I think this is a manufacturing issue (bad batch perhaps) or it's part of the accepted tolerance as the spin lock collars work fine. For me it's slightly annoying as I use 1" spring clips to secure the weights when doing non maximal lifts. Normally these grip the thread very well, but this bar having a slightly narrower thread, I have to angle the spring clip so it rides across one more turn before it gets a good grip. Only takes 3 seconds but it shouldn't be that way. If you choose the non-threaded bar it may not have this petty problem but it wouldn't have spin locks either.
The chrome plating isn't the best I've seen on York products but the knurling is well formed and wide allowing for many grip positions. Overall weight is about 10kg. The bar can safely handle 120kg.
A very good bar, but it just misses the top rating. Consider it, or the non-threaded version, if you need an upgrade from the 5' bar.
