the best you've ridden is the best you know.
^that is the cleanest chain that i have ever seen![]()
wow...3 months?? That looks terrible. Not only are they being chewed up, but they're already gettin that fish hook to 'em. Thanks for the heads up

Sounds like thrust is using some junk ass aluminum. Hence why they were probably cheaper.
+100000000 on Driven.![]()
I now know what im going with next..Driven.
Last set I got was Vortex..only reason I got these were because its the only thing the shop had and I HAD to have something that day(broke 3 teeth off on old shitty sprocket). Never again..my vortex is wearing like crazy as well.
vortex are not hardened aluminum so they do wear fast, I'm sure these Thrust probably aren't either... BUT DAMN thats a lot of wear. Proper chain slack?
