Hi,
Recently upgraded to Shimano 105 r7000 about 3 months ago. All fine until a recent ride. Changing gears all seems fine, but shifted down to smallest gears on a long fast stretch of road and then it started skipping or slipping on certain sections of road where it became quite rough. Everytime I hit a section of rough road it would skip or jump then rectify again.
Is it a simple step of slack cables or a slack chain
