I recently switched my SRAM 1x12 Eagle SX drivetrain from a 30 to 34 direct mount Chainring. I also bought a new chain to accompany with it. Chain length was measured as the sram service manual advices. Put the chain around the largest rings and have 4 links overlapping.
The cassette has around 700km.The previous chain had around 0.5% procent wear.
When going into the highest gear and one cog beneath it by chain slips when applying pressure. The other gears work fine.
I degreased the new chain upon arrival since it was very sticky and applied dry lube after washing off the degreaser and drying using a towel.
I read online and some advice the cassette need to be replaced but after 700km to me that would be really strange. Could the chain slippen have something to do with the derailleur height? Which might be different since my chainring has chained or is this not correct?
I assume a larger chainring does not have impact on the left/right adjustments of the derailleur?
