Reba came on a new bike two years ago. Haven't touched it since (never added air, never serviced). Probably have 100 hours on it.
Last ride it seemed really squishy. Got out shock pump. It was at 35 psi. Pumped it to 105 psi (RS recommendation for my weight).
After pumping tested sag. Sag = 0%. Stood with front wheel between legs, put all my weight on handlebars, lifted legs to suspend myself on bars and still no budge. Took all my effort to get any movement.
Did some googling / reading. Heard about the burp trick.
Burped air side. Tons of air. Came out for probably 4-5 seconds. Some oil too (see pic below).
Attempted to burp other side: nothing.
Tested sag. Sag now = 20%
I guess I can keep burping it as needed.
But planning on "50 hour" service so and figured I might as well take a stab at a longer term fix while I have it apart.
Based on symptoms described above, can anyone tell me which part / o-ring / seal is the likely culprit? Or what I need to do to fix?
I found another thread where someone suggested "Your spring is leaking into the lowers. You just need to replace the lower seal head."
But I don't see "lower seal head" listed on the SRAM diagram (see page 6 of pdf).
Could anyone confirm whether this is a lower seal head issue?
And, if so, translate "lower seal head" to the official name listed on the SRAM manual so I know exactly what I'm looking for?
