I have the chainboard on my Winter bike, a Kona Lanai. Fitting it t was,... a bit tedious. I fitted it for chain protection only. I added a cowl to the left side of the front ring, to get better protection from road spray from the front wheel, which is running Cascadia fenders by the way. It has pretty much been a success, haven't had to clean the chain yet, and only lubed it, twice? It is almost a certainty you will need to do some trimming for a perfect fit.
