I decided against the Kappa Panniers as the SW Motech Alu-rack and the soft luggage adaptor combined were �100 cheaper. I already have various soft luggage for my other bike so it makes sense.

The advantage of this system is that the luggage adaptor can be removed in a few seconds and you hardly notice the Alu-rack. A bit of a brute to fix due to my lack of skill in these matters but I am very pleased with the result.

Thanks for your help and rest assured I will not leave my soft luggage bag unattended for long!!
