Hello,
I guess this is a really basic question but I couldn't find a general ask thread;
Question
are components of the rear and front drivetain independent as long as the shifters are compatabile with both front and rear-deraillers.
Background
I have 105-5800 groupset and I am updating the chainset to a shorter 165mm. As I can't find any 5800 in stock I am going to get R7000, I believe this requires updating the front mech as the 5800 FD and R7000 FD are incompatable based on the shimano compatabilty charts.
Looking at these charts the front drivetrain and rear drive train charts are indepdendent hence my question. I guess I don't see a reason why they would need to be but thought I would check.
If there is a better place to post this mods please delete (and sorry!!)
