In my experience, most trackies now use 3/32". Regardless, wroomwroom isn't a trackie. He's using road stuff on the road and finding that his chainrings are completely done after 6,000 miles of use. Most roadies will tell you that this is unacceptable. Moreover, in my time as mechanic for a fleet of velodrome rental bikes, I never saw a worn out chainring, and these bikes were often 15 years old and running 1/8" chains on 3/32" rings and cogs.

Regardless, I'm simply trying to make one point: 3/32" chainrings should last quite a bit more than 6,000 miles, and if they do not, something is wrong.
