JPS,
XRAY have listened to the feedback given by their customers and released the 2011 low profile bladder to make the shocks easier to build and to allow us to tune the rebound more effectively.
The old style bladder is very deep which makes it quite difficult to bleed oil out once its sat down fully. The reason it was easier the first time you built them is that because they expand after some use (just like silicone O-ring's do). If you have to run the old bladder again, here is the technique I always used:-
[*]Fill the shock body, move the piston up and down a few times and wait for the air bubbles to rise out. Leave it so the shaft is fully extended.
[*] Place the bladder on top of the oil and using an allen driver, push the side of the bladder in while you slowly lower it down. This allows the excess oil to escape effectively. (This should give 100% rebound, with no excess pressure in the shock)
[*] Now to get less rebound, lift the side of the bladder slightly so theres a little gap for the oil to escape from. Now push the shock shaft in slowly, which should let some more oil out. When you have stopped pushing the shaft in, slowly squeeze the bladder back down as the oil stops coming out. Usually if you push the shock shaft all the way in, this should get you pretty close to zero rebound. You should get used to using this tecnique pretty quickly and it becomes easy to set the rebound accurately.
If you would like some input on building the shocks with the new low profile bladder, feel free to ask.
All the best,
Phil Chambers.
