Good poin! Now, less teeth means sharper chain angle as well as less links sharing load at the same time. That's critical for the front, the rear one is pretty big in all combinations.
So 7 TLC, instead of 3, vs more teeth to share the load. I have no idea which is better.

I have no idea too just reading gearingcommander stuff  :lol

The reason I have done the front only was when I tried to fit the new chain and the bigger rear too there was no place left and I was not able to put the chain because of the bigger rear. According to the specs it must fit but it wasn't.

That's what I was thinking -1 on the front wont make much difference to the rear wheel position along its ajustment slot, but to get the same result by just doing the rear sprock by going +3 then surly that would be just too much for the chain to fit.
Is there such a thing as -1 front and +1 back
