The closest local dealer is now 30 minutes away by car on a good day when traffic is light. So I called Specialized a couple of weeks ago to see about getting actual parts breakdown, maintenance schedules, and any other instructions that might be available to assist in doing my own maintenance that are specific to their 2016 Roubaix frame. Unfortunately, that’s only provided to authorized dealers. Not sure why parts numbers need to be kept hidden from the cyclist.
