More likely there’s water ingress and it’s slightly frozen
I had issue on dropper post cable took the inner out and it was a light coating of ice all around it
Seen a few ways on bedding pads in
Huge sharp stoppies
Or slow brake dragging
I find Shimano bed in really quickly but I always rub the pads on a hard surface to take the top layer off first
So I recently bought a second hand shape it UP link to put on my newly mulleted V2 E160
Has anyone else done so and can advise on best settings I should run
Cheers
