Any advice for the kind of relevant info I should include?
I once worked with a film director who would answer any question about what he wanted with, "Don't deny me any riches," meaning he wanted each possibility scripted, which made an enormous amount of unnecessary work. I hated him and twice since refused to work with him.
I were you, I'd start by compiling a list of references to previous discussions on the board, including those on other subjects containing references to the Chainglider, as a sort of reference zentral and to avoid writing tedious iteration of material already covered, such as choosing the correct Chainglider components, or distinguishing between the series, all of which and much more already stands on the board. Also make a reference to Chaingliders that don't exist yet but would are wanted by a group of Rohloff riders, the 36-tooth chainring brigade; do this at the end of your brief section on matching Chainglider components to each other and to the transmission on the bike.
In the main section of your report we want to know why you took the decision to install a Chainglider, because your intention and expectation determines your assessment of the outcome. Follow that with a very brief description of each of your tours -- with URL references to longer descriptions elsewhere on the board, so we can understand the challenges you put to the Chainglider. Then its performance. Your stats will come in handy here; cyclists adore stats, especially the ones they understand. Finally, a succinct personal assessment, often seen in the form "why you would recommend it (or not) to a friend".
Don't do as I do and write descriptions; where you have a photograph, use it, and make your point in the caption; some of my most popular bicycle articles aren't articles at all but photo-essays with minimal text clarifications.
Enjoy your tour!
