As long as it shifts smoothly into and out of the big/big combo (i.e., you can't feel any binding) you should be good. Cage angle doesn't make much of a difference.
I use the big-big + 1 complete link (i.e. one whole set of inner and outer plates) rule of thumb and it's served me well. The caveat i would add is that "big big" means the minimum amount of chain that would go over both cogs and still *easily* close--i.e. it wouldn't be a stretch to connect. Then add one complete link and cut from there. On Friday, October 19, 2012 2:24:56 PM UTC-7, Patrick Moore wrote: > > I just put a new Sachs P 48 (?
