Zinc coated bars will most likely get a patina over time, however this does not affect the barbell's performance and function.

KnurlingThe knurling of this barbell is very well crafted. The knurl is consistent throughout the entirety of the barbell - something that we look for in high quality bars. The knurling stops just at the collar, so those who grip the bar at its widest, for the snatch, will still have plenty of knurling to hold. The knurling is not too sharp that it cuts up your hands, but it is still aggressive enough to make for a nice contact between hand and barbell. There is no center knurling on the bar so it will serve those who do high volume workouts as well.
Oscillation (Whip)The Bar has a nice balance between a weightlifting bar (with a fair amount of whip) and a powerlifting bar (a more rigid barbell). The bar is balanced, which will make it comfortable for most lifters across multiple disciplines of strength and conditioning" - Review on Knurling, Oscillation (WHIP), and Spin provided by The Thirteenth Strength Community
