Hi,
I have mounted today the Heavy Duties pannier system. I have decided for 2 X 48L. Due to the fact that I have LoeVince pipes, the installation was very easy and quick. Panniers are well made, when mounted on the rack they do not move a mm. I do not have yet the locks but they will arrive soon. I went for raw aluminium without powder coating:
1. do not care so much about the looks
2. cheaper
3. figured out that they will be scratched soon anyways
