Two technical questions which nor of them are DH/FR related……..

1 : How much pressure inside the piggy back of a DHX Air 4.0 ? And how much in the main chamber for a 90 Kg rider ? Also how much would the max pressure be for both of the locations ?

My own guess is 180-200 In the piggy and Max 250 And for the main 20 % of SAG would go right with a 300 Max ha ??

2 : Do Cross max SLR wheels differ front and rear ? Some one is telling me the seat angle on the nipples differ and he cant lace the wheel I sold him on his rear hub….?

Right or just nagging ?
