A couple years ago, I bought my first "more-than-recreational" road-bike and it has a triple chainring. At the time, I thought more is better, but I'm finding out that's not necessarily the case. Seems like the extreme chain angle doesn't allow me to use many of the gears effectively.
So now I'm thinking, as the teeth begin wearing down, that I'd like to go back to a double. What are the issues here? Do I need a new derailleur too, or a rear cogset? Do I need to add/remove chain links? Just wondering how big a project this may grow in to!!!
