Olympic Barbell Collar for 2" Olympic Bar

This is a review for the type of cheap twist lock olympic collars shown on the right, not the left. (I don't recommend the one on the left - with just the screw - unless you don't care about protecting the sleeves of the barbell or dumbbell you'll be using it on.) The one on the right has an inner "pressure ring" that's familiar from the more expensive Ivanko collars. I like to think of this as a cheaper rendition of that style of collar. The pressure ring will get between the tightening screw and the barbell sleeve, and will help to keep the sleeve protected - just like with Ivanko's collar. But since the pressure ring of this collar is more flimsy (e.g. narrower, thinner, less thick), it can get loose over time. Also, the twist locking pin is thinner than Ivanko's, and can dig into your skin, making tightening/loosening uncomfortable. But judged on its own merits, it provides good value and performance for the price. Once locked in, it holds the plates in place as well as many collars three times its price. It'll also work on specialty bars with a narrower sleeve diameter. It's a good option for someone on a budget. (For myself, after seeing the difference that the pressure ring made in terms of performance and sleeve protection, I went and bought the more robust collar with the same design from Ivanko, and do not regret it at all.)

Not the best solution for collars, but did get used back in the day. Will cause cosmetic damage. Not using today.
