I’ve been asked about mounting Ortliebs on the folding Bike Friday Tikit rack so here are some photos. Note that I use my Orliebs on several racks so I mount the upper/lower hooks in a middle position that works okay with all my racks, but isn’t necessarily ideal for any of them. If I was going to tour with my Tikit I’d take 5 mins and adjust the hooks to fit this rack better.
Generally speaking I like to mount my panniers as far forward as the rack and heel clearance permit for better handling. It’s worth playing with your bags/racks and trying out a few different options to see what you like best.
