In the bottom of the rack go for the lower hole, on top choose the hole in the middle and as they say Bob's your uncle.
After I posted a pic on the Ogre/BC group someone said his Ortlieb bags don't fit on it. So I took the front bags out of storage and put one on. No problem. It fitted just fine. I think Tubus and Ortlieb - both German companies - work together on their products. This guy probably did not have the front bags.
I have half a mind to make a video on the process - that is how to instal it on the bike - but it seems so simple that it might really look stupid when turned in to a how to video. But then when I googled the subject "Tubus Duo on Bridge Club" there is nothing. So I might just make one for all it's worth. Perhaps the best idea is to make one showing how it is done on the Bridge Club and the LHT. That might have some takers.
