FAQ
Questions, answered straight
Grip plates or plain plates?
Grip cutouts help most on 35 and 45 lb plates, which are awkward to carry flat. Small plates gain nothing from grips. Many owners mix: grip for the big plates, plain for change plates.
Why does the paint chip at the hole?
The bore slides along a steel sleeve under load, so hub paint wear is normal on painted iron at every price. It is cosmetic. Bare, oiled, or enamel finishes show it less than thick black paint.
