And the fun continues.
I have a 2018 rear brain due next week from Brazil. Photos and measurements to follow.
I've had a failed 2018 in my hands once already, some new tooling will be required, but now Specialized (Rockshox?) are giving the tooling needed for a 50 hour aircan service to dealers.
The redesign now uses a bladder instead of an IFP, bladder pressure was dropped to gain small bump compliance. I'm hearing stories of a lot of failures, along with a damper rod or bearing head part needing replacement due to parts out of tolerance.
I'm perplexed at the moment how dropping bladder pressure to gain small bump compliance doesn't cause major issues with pressure loss at the main seal head after full stroke compression events that require more oil return then the bladder pressure and hose cross section area can satisfactorily achieve, letting aircan air pressure to pass the main seal into the oil side.
