I'm selling this after purchasing it on a flea market site, as I haven't had a chance to use it. The handle doesn't spin freely, but it rotates smoothly with a little force, so I don't think it will affect your training. Below is the product profile description from when I purchased it: Used with BODYMAKER Home Gym DX. Purchased new, but used. No rust. Manufacturer model number: CA8 Body size: 15.5 x 14.5cm Grip effective width: 11.7cm Diameter: 2.5cm Diameter of the hole in the triangular plate for attaching the carabiner: 1.3cm no13-00
