Drivetrain longevity. What are you getting

[MOG]

Had my H15 Orbea Rise since early Feb and have completely precisely 742 kms in total. About 20 % foul weather, the rest has been pretty dry to be fair. Just had to fit new chain as it was well over 1.0 on the gauge. Also checked lower pulley as it felt a bit stiff and on removal found 2 balls missing and one ball incomplete. SLX 12 speed. Is it just me or is that a bit shit? TBF the cassette and chain ring look to be hardly worn.

12 speed GX on my Rail and got 2,000 km on first chain and cassette mainly riding dry conditions. On my second GX cassette and running two GX chains this time and swapping every 500km and have just clocked over another 2,000 km and it still shifts like a dream. When these eventually wear out, I'll be running X01 chains with the hard chrome pins as they (reportedly) last really well.

1500km on my first chain (KMC), and still on the deore 12s cassette at 2500km. Have got a 12s slx cassette ready to fit when required.
