The PR Max Power bar was designed specifically for powerlifting movements. The knurling is medium-sharp with a "grip you back" black manganese phosphate coating which provides all the grip you could want without the need for cheese grater-sharp knurling. This is the BEST bar ever for any gym that does not allow chalk -- the knurling/coating combo is that good. We have also extended the loadable sleeve length to 18". The extra 1-2 inches of loading space compared to conventional power bars really comes in handy if you use bumper plates in conjunction with steel.
