Robert,

Those small holes are indeed for mounting racks, but crofters bike has
a seat post mounted rack so the gear doesn't crunch over bumps. THe
bag has drop down panniers either side and it mated to the rack and so
slides on and off easily with a nice 'click'.

I think like you Robert, that if its light and bulky - put it behind
on a seatpost mounted rack. If its heavy, mount it off either side of
the main frame, central and down low.

CHeers,
John
