I just installed a used rear derailleur to my road bike with cables and housings and all.
I am having some difficulty in getting a good position on it.
My 1st question is regarding cable housing. How long should I cut it? is there some formula? Does it not matter at all?
The main problem I am having is that the 1st 2 or maybe 3 clicks of the shift lever dont seem to move the pulley from the small cog. Of course as a result it does not make it up all the large cogs.
I have watched dozens of online videos and yes I read the park tool website and the sheldon guys page on RD, but still need some pointers.
