The front rack(s) are a cheap bag support of Ebay (Abaxo, I think) and a Jandd low-rider rack. I had nothing to match the rear rack, so I did not try to go buy something fancy (Surly or Jandd Expedition). The mirror is a simple bar-end plug mirror I got at REI a long time ago. I assume they are still available. Ergon grips with A Rohloff is expensive because you cannot buy a set of Ergon's for only one grip shifter. You can by one for two grip shifters, and one for none; then only use half of each package. You would think they would come out with a special "Rohloff Edition". Even at a 50% premium, it would be cheaper than buying to sets.
Fenders on an Ogre require some dedication. I am running Planet Bike's because they are about the only ones made for 29'ers. There are several problems. First, you have to run at least one set of Surly Monkey Nuts for the rear fender to work at all. Even with one set installed, the front derailleur cable will likely rub on the fender. Metal cable; plastic fender, we all know how this will end. You can run a second set of Monkey Nuts (for another $25) and push the rear axle all they way to the end of the dropouts, or you can dump the front derailleur and run a 1x?? setup. Even if you solve that problem (as I did), the fenders, with really long stays, are too flexible and rub on the tires when you hit bumps. I fixed this by attaching zip ties between the fender stays and the racks 1/4 to 1/2 way along the stays to stabilize the system. You probably cannot see it in the pictures. I still get some rubbing when the going get insanely rough, but it does help a lot, and I am not sure how much better you could make without some sort of steel fenders which do not exist.
