I spent the morning today fitting my Tubus Fly Rear Rack on the PROMPT D902. As it does not have any eyelets for a rack I also had to intall the conversion kit and rear axle mount kit. After some fiddling (the instructions are not great), the cutting down of some bolts that were hitting the rear cassette the system was installed. I have chosen some Deuter Rack Pack Uni Panniers and some separate waterproof inner sacks.
The next stage is to go for a test ride. I am a little concerned with all the mecano like bolts rattling loose but I can report back on this after further testing.
