I am in the process of building a road bike.
I currently setting up my rear derailleur. I can't seem to index the gears. I have set the high and low limit screws.
I can shift up the cassette (small to big cogs). I can shift down the cassette to every cog until the 5th one, any shifting down the cassette from here on results in nothing happening or certain gears are jumped.
Everything is new. I can't see any kinks anywhere although it is internally cabled. I am using an (11 speed) 11-32 cassette and a medium cage derailleur, all Shimano 5800.
Appreciate if anyone can provide any advice.
