Hey guys, does anybody know anything about the vortex PTFE black sprockets? I tried doing some searches, but they didn't return anything informative. All the results fell into two categories: People selling it and less knowledgeable stunters. The impression I got is that there are a lot of Vortex haters, most of which appeared to be very ignorant. Yeah your drivetrain will wear out extremely fast if you don't take care of it. The most I could gather is that the PTFE is the same as the teflon coating on a frying pan. Ever used a pan without it? Seems like a pretty cool idea, but if it was that amazing wouldn't there be more buzz... So does anyone have any firsthand experience with these?
