Disc calipers

I'm replacing my RS505 shifters with 105 7070.

Looking at compatibility charts, the RS505 callipers will need changing too (as well as hoses). I have the shifters already (warranty replacement), but struggling to find a rear calliper due to stock issues.

Am I right in thinking the only difference between front and rear callipers will be the bolts that fix to the frame - longer bolts at the rear - or am I missing something? I have some spares kicking about in the garage.

    There's no difference between front and rear calipers for Shimano. The mounting hardware and adapters (if you need them) will be different, but you could reuse those from the current brakes.
