Before removing the air can, do I need to depressurise the piggy back on the shock, or just the main valve? Not serviced a Debonair shock before, and youtube videos arent conclusive!
I've got the adaptor to reinflate if necessary, but suspect that repressurising back to 250psi might be tricky.
thanks

I haven't opened that particular shock myself, but SRAM's service guides are excellent.
There's also a decent MBR vid on Youtube that will answer it for you.
no. you dont need to touch the piggy back.
That's the thing - the SRAM / Canyon instructions from 2014 had an additional step 3
"Use a Schrader valve tool to remove the IFP reservoir valve cap.
Use a small hex wrench or pick to depress the Schrader valve and
release all air pressure from the IFP reservoir.
Once the pressure has been released, depress the Schrader valve
a second time. If the Schrader valve is able to move, the shock has
been completely depressurized.
If the Schrader valve does not move at all, the shock is still
pressurized and will need to be sent to an authorized RockShox
service center for further service."
Looks like this has been removed in the service link above.
No need to touch the piggyback unless you are going to service the damper aswell. If you do you risk ending up with the IFP in the wrong place and you will need the rockshox adaptor to re-pressurise with air or preferably nitrogen.
