People, check your chains! SRAM Transmission riders, beware.
I usually check chain wear about once a week. I have two chain checkers, a Park Tool CC-2 and CC-3.2, and until this week both showed wear below 0.25, even after roughly 800 km of riding.
What I didn’t realize is that SRAM Transmission chains require a dedicated chain checker. The older tools are not accurate for these chains.
So I bought a Park Tool CC-4.2, which is designed for SRAM Transmission. To my surprise, it showed my chain was nearly at 1.0% wear.
I replaced the chain immediately, and today I’ll find out whether I caught it in time or if the cassette and chainring have already suffered too much wear as well.
Lesson learned: if you’re running SRAM Transmission, make sure you’re using the correct chain checker.
