Anyone got any experience with %SUBJ%? I asked MRP about 200hrs service instructions for Stage but they sent me instructions for 200mm Groove which cannot be any more different (dual crown, upside down, IFP instead of a bladder, but with a piggyback). All I've found is this video which looks legit. Of course, it showcases $50 proprietary tools... Since bladder and not IFP, can I replace oil just by pouring old out and refilling with new through the top opening? I've been expecting a bit better documentation of their service steps.
