So I'm trying to adjust and fine tune the bicycle, but there's something that quite doesn't match up anything I've seen or read online about rear derailleur adjustment, most manuals go this way.
- Adjust limit screws.
Fine tune cable tension.
2.1 if it's not going from the largest gears to the smallest, tighten, remove tension
2.2 if it's not going from the smallest gears to the largest, loosen, add tension.
My problem is that after getting the limit screws right, it fails in both directions, that means, going from the largest to the smallest and from the smallest to the largest both fail, so adding and remove tension won't work as fixing one would only make the other worse. However this only happens in the higest gears, the climbing gears shift perfectly, where the fast gears would randomly fail in both directions.
Basically everything is new, and yes, it is definitely matching parts, it was working well a week ago, now it feels like the changes in the smallest cogs are too small to trigger anything.
I understand how all the mechanism works with the exception of the B-screw.
Just a comment when I set up my limit screws it seems like I can push the derailleur a couple of millimeters in the horizontal axis and an entire centimeter in the vertical axis, only in the smallest cogs, I could swear to god that's why, it's sticking to the previous position and hence it fails in both directions unless cable tension is able to overcome that, except that there's not enough cable tension to overcome the stickiness of the derailleur in the smallest cogs, but the derailleur is new, some sort of setting or what?
EDIT: I just added oil to the derrauilier and it seems less sticky and it got better, but it still fails a lot to switch.
