105 R7000 front derailleur with 105 5800 crankset I was thinking of upgrading my Tiagra derailleur with new 105 FD-R7000, but then I read that it might not be compatible with my 105 5800 crankset because the new R7000 crankset has different spacing between chainrings. Will I have a problem if I upgrade to a R7000 front derailleur with 5800 crankset?
Shimano lists the FD-R7000 front derailleur as compatible with the FC-5800 crankset in their products compatibility information, but the R7000 crankset wont be compatible with the old derailleur.
