Got some Olympic sleeves. Good price, fast delivery. Excellent.
Got two. Good quality and heavy.
I've put them on the ends of my Swiss bar, as its standard.
Pricey a little, but best solution as they are longer than most.
The caps come off, which is handy as they will slide all the way to the end of the current standard sleeves.
Fits and works great on the York 1 inch leg extension machine well made highly recommended
