I vaguely recall seeing this bar and have never worked out with it, but one recently popped up for sale on Facebook Marketplace from Elissa on 1/25/2022.
Retail is $124.50 and tax and shipping takes the price to $169.41 so the Facebook Marketplace price of $75 is a good value.
The question is what would I do with this and do I want to store yet another odd size piece of equipment in the gym. It seems to bridge a tricpes bar and ez curl bar into a fixed bar cast platform that could certainly be a big plus in a commercial training facility. There are way to many idiots who cannot clip their weights or keep a bar steady.
For me, it would be took much of a uni-tasker as I rarely do accessory work at home and would be better off buying a triceps bar for 1" plates.
