Which cogs were worn? On my half-bike, I have a compact crank, and so I'm usually in the small cogs on the Record cassette. These are steel, but still wear out too fast. I've replaced these several times, while my larger Ti cogs are still fine.
I used this cog switching as an opportunity to go from 13-29 to 12-29, by skipping the 16t.
