I have the same problem with my 2017 ruby di2. Very little travel with future shock and have had cartridge replaced once already now the problem is back again. Also the headset is constantly coming loose, have had it tightened at least 5 times lately it’s after every ride pretty much. Also has strange noise when pedaling under load. Apparently this is because of the loose headset. The solution for the small travel of the future shock was to insert the stiffest spring to stop it from bottoming out, just ridiculous, why offer three spring types. Am going back to bike shop tomorrow and will ask for my money back. This bike is an expensive lemon!
