I purchased this bar based on the advertised diameter of 28mm and the end cap clearly states 28mm. However, this bar is not 28mm. When I removed the bar from the shipping carton the bar felt larger than 28mm, and it is. I have a micrometer and this bar actually measures at 28.68mm, hence the 3 Star rating due to the inaccurate advertised diameter. The .68mm larger size might not seem like much, but it does make a difference for me. Still, I am planning to keep the bar as I can still use it.UPDATE: I was contacted by Philosophy customer service regarding my discovery that the bar I received was not as advertised. The customer service representative was very helpful and I can confidently recommend Philosophy gym equipment as they do care about the customer experience.Great value for the priceBar was delivered in perfect new condition and arrived early. No scratches, no rust, sleeves spin easily and smoothly. Weighs slightly over 33 lbs. There is a 52 inch 28 mm inner bar so the bar fit on my Titan T3 power rack easily with three inches of play to each side.The sleeves are 9 inches with bevel or 8 and 3/4 inches usable length. If your barbell clamps are the typical plastic 2” wide type you have 6 and 3/4 inches for plates. I bought an aluminum clamp that is 1.5 inches wide to allow extra space for bumper plates.I won’t ever lift near the 700 to 800 lb capacity of this bar, but did lift 300 as a quick test. The bar had no issues. If you use tall thin 45 lb iron plates, the most that will fit this bar is 5 plates per side. That works out to practical max weight of 483 lbs (450 plates and 33lb barI lift in my home garage so this six foot bar is much more practical than my previous 7 ft. bar to move about. Further the 52 inch span allows me to rack this bar for easy plate changes unlike my 5 ft bar.This Philosophy bar is a great, more convenient addition for my garage gym.I've got a small area to work out in and it fits perfectly without hitting anything. Good so far.I've used this bar for over a week and it is great!. The weight collars rotate very smoothly, and the bar itself is just as advertised.Exactly as described. Feels solid, feels quality. Would buy again.I needed a shorter barbell for my home gym and tried out a few others before finding this one from Philosophy. Every other 15kg bar I found on Amazon had a 25mm thick handle, but thankfully this one from Philosophy has a normal 28mm handle. Quality is great, couldn’t be happier.This bar is as you see and would expect. Nice bar. Seem like all the bars I use at the gym I go to. I got the 6 ft for my kids to start with. Like my purchase.
