Rail (625Wh) 38t chain SRAM chain ring life span

[NETTA17]

Hey,
I have 2500km .
The 2nd chain is 0.75% already ! - Clean & lube it every ride.
Using Genuine SRAM GX Eagle chain. I don't know the reason .
I wonder if it causes by a worn chainring.
Any idea of the estimated lifespan of it & how I can check if it is still fine?
Cheers.

I think I replaced the chainring once in the past three years with an ethirteen 34t. I noticed a problem with the chainring when I started getting chain-suck. That was at about 8-9K km. I think I replaced 3-4 chains during that time.
I keep my cadence at about 80-100 and rarely use turbo mode.

Edit for caveat; I switched over to Hyper Glide chain, XT cassette and AXS GX derailer. That may have helped. I know it’s a hack but it works for me.

that rate of wear sounds a bout normal to me! Assuming you are not getting any slipped gears etc you have 2 choices now. Either keep running the existing chain until it gives problems at which time you wil probably need a new chain, cassette and chainwheel..............or change the chain now and see what happens. If the cassette is worn you will get gear slippage especially on the cogs you tend to use most. If the chainwheel is worn it will be noisy at best, cause chain suck at worst. In general chains wears the cassette and chainwheel not the other way a round. Steel chainwheels are cheap as chips so always worth changing it when you change both cassette and chain.
