Looks legit to me - the knockoffs don't cut the helical ball groove for cooling on the slipper-side endcap(just slots). The stock spur is cast, hardenened steel and we have cnc steel and Delrin upgraded spurs as well. The site shipping to any international location will quote $30+ for almost anything, but we can ship 1st class for smaller orders if we arrange it through email(site won't allow it). :)
