way too many variables...
what bike, what length chainstays,
how well packed, how bulky,
how much do you weight, etc....
just load up and try it out.
might be acceptable for you.
if you don't like it, move some
onto the front rack.
if only 15kg, should be okay.
i usually have about 5kg in each
pannier on the rear, then add one
or two 1.5L bottles of water along
the way....so 12-13 kg, with 3-4
kg in handlebar bag.
