Maybe even Sram motor? Love my Rail 9.8, but it is unnecessarily heavy, all the battery fixing hardware lock etc and battery cover weigh far too much... plus the motor rattle and no doubt the battery makes some noise too, no matter how well its adjusted... I reckon you need the extra full fat...
Order from a Trek dealer,
screws 579092
bottom w555588
Top (handle) 572657
battery cover part number varies , mine is carbon red smoke/lithium grey part number 601842449523 , but you might get more options if you search for that...
I’m waiting til march for new battery cover for spare… until then , I bought the handle part and screw set , screwed the handle on , then all you have to do is undo the two bigger screws on the bottom end and the two smaller screws on the top end … it leaves the bottom part screwed to the side...
Had the same trouble adjusting pressure on Zeb select + on my Trek Rail... (RockShox branded pump)...swapped the valve core for one from Schrader car tyre valve and was sorted instantly ... RockShox super deluxe ultimate rear shock wasn't easy to adjust pressure on either, so swapped the core on...
No probs, I tried loads of settings, don't use boost much, so set it to low to use for tech climbs, because the self adjusting trail mode seems a bit vague when using varied cadence and pedal pressure on tricky climbs
Had the same problem too, super glued it back on, and to make sure it doesn't fall off again , I used some heat shrink tube over the top ,then squeezed a bit more super glue under the heat shrink for extra security. been alright since.
