Shifting slips on climb

Hey guys, I recently had some shifting issues due to a cable problem. That issue has been resolved. Now I have noticed that when I'm climbing hard and mashing at the same time, the gear would slip (jumping like 2 cogs) when I shift up. I don't think this is normal, correct? It would make like a clank sound then jump up like 2 cogs. What can I adjust to help with this? This would not happen I don't mash the pedals and spin up a climb.

I do not know what your drivetrain is but i recently had the problem on a Campy 10 speed set up. My problem was after about 25,000 miles the springs in the brifters were worn. I rebuilt my right brifter and everything is as good as new.

I have sram rival but the components are new probably less than 1500 miles on them. It shifts perfectly on the flat. Just when I climb hard it does it.

I highlighted your problem. Don't shift under full load.

Always ease up on the pressure while shifting.

All those features, ramps, shorter and skipped teeth, that index shifting need ..
make for a tendency to ghost shift.
