• @snoops yep, i had an experience where i bought some gp5k off someone on ebay and noticed (of course only after money had exchanged hands) very quickly that there was something very off about them. the bead ended up being a total shitshow and it slipped off my front tyre mid ride. believe it or not i bumped into this person again selling stuff on this forum.

  • Well, luckily mine haven’t had any failure like that, but the compound feels different when I’m riding and the fact this centre mould line isn’t wearing is suspect. Set-up and general tubeless performance has been fine. Hope you didn’t sustain any injuries.

    Is there any way to confirm if they are genuine? Any mark or code that I can reference?

  • hard to explain but in my experience the gp5k is a pretty rigid tyre, all around it just feels quite sturdy and bulletproof. The knockoff felt far softer and even the wire bead didn't feel as strong as the original. sorry, it's not really a great explanation but i think the point is if you've tried some gp5k before, and these not feel quite right then they're probably not real.
