## Customer feedback

Customer feedback highlights perceived quality, sturdiness, curl performance and value, while also reporting some missing tightening or set screws. Opinions on comfort and grip are mixed, so the angled, knurled design may not feel the same to every lifter. These reports are customer perceptions rather than confirmation of the listed materials, rotating sleeves or capacity.

## Frequently asked questions

### Which weight plates fit this bar?
The listing says it fits standard 2-inch Olympic plates and collars. Check the actual sleeve specification against your plates before ordering.
### What is the bar's stated maximum capacity?
The details list 90.72 kg, while the title and feature copy claim 500 lb. These are inconsistent listing claims, so confirm the rating for the selected configuration before loading the bar.

The details list black powder coat, but feature copy also describes a chrome coating. The finish is not consistent across the listing.
