We've just updated the Setup Guide. Again. There is a lot of new information, including a nice size guide. One very helpful page that has been updated is the Front Derailleur Compatibility Matrix. With the advent of direct mount derailleurs and lots of 2X systems, it's not as easy as it once was.
Our most recent Setup Guide covers our current model lineup. If you're looking for info on a previous model you could well find it in one of our legacy guides, handily listed below.
