Question: what is the circumference of the grip ? or the diameter ?
Document: Now the 'hard as hell' spring clip is very easy and holds the weights ok, but the other I can slide it around on the sleeve.2. The dark finish makes it hard to see where the knurl-less parts are, which makes finding my grip spots slightly more challenging that I want.
Needed a barbell for my new home gym... but not just any barbell.Primary use is squats and deadlifts.The ends spin nicely and there's no knurl in the middle of the bar (Perfect! )The areas with knurl aren't too deep to cut the crap out of your hands, just enough to get a nice solid, comfortable grip.
The added spin is easy on my wrist. The sleeves on the bar show some signs of chrome coming through after adding and removing weight, but I do not expect this bar to be pretty since I am  droping it from over head with #200+ on it. There is zero flex on this bar, may not be ideal for olympic lifting, but I have no issues performing olympic lifts. The knurling is good, no issues with grip.
I was skeptical buying online. Read ALOT of reviews....Then I finally took the plunge. So far nothing but positives. No excessive oil or grease on delivery. Black chips but that's a no brainer. Bar is close to if not exactly 45lb. Good enough. Bar grip is rougher than your average gym so you'll have to man up. No complaint there. Has held up nicely during OHS and cleans.
This is a heavy-duty bar. The black finish scratches off easily, but I figured it would and didn't care because of the price. The knurling is not too aggressive, so it won't tear up your hands, but there's enough depth for effective grip. Unlike some of the other reviewers, my bar was not full of oil. I suppose it has a light residue, but nothing worth worrying over. It'll wear off with use. I have some observations specifically as a powerlifter.
It's a bar, but it just looks so nice. Yes, over time it will start to scratch up but who cares, if you're trying to get bigger, stronger or whatever you shouldn't be worried about that.- Some reviewers have complained about the knurling being too aggressive but after using it for month I feel it's just right. On other bars I've used when I do lifts such as deads as I start to fatigue I tend to start losing grip and would have to readjust my hands the last few reps.
I also like the fact that the bar itself doesn't have a smooth finish so even there's very good grip on the non-knurled sections as well.- It's rated for 1,500lbs. I will never be able to push that kind of weight and I don't know how accurate that rating is but I don't doubt this bar can handle very heavy weight and can take abuse. Not only does the bar look nice but it's built tough as well.- The ends are capped.
the bar seems great ive had it for a few months now and my only complaint is since its black it scratches and turns sliver in areas!! !
overall an excellent bar.
i think i need a lot more time with the bar to write a solid review (will be back :) ). so far, bar feels great and solid. i use mostly for powerlifting but sprinkle in some oly lifting.
