Essentially the pressure down stream of the rebound piston draws a vacuum and the rod seal can bend backwards and suck in a bit of air on each stroke. This is an another reason to add a charging sleeve around the bladder to maintain this positive pressure.
same applies to the fox fit cartridge too then.
ps, the charger tube will be maintaining a positive pressure, adding pressure around the charger tube will increase pressure, reducing sensitivity, no? hence retuning required to accommodate this.
i really cannot complain about the performance of my pikes, there is no situation where im left feeling i need more, really supple, even though im at 110psi, which is a lot more than people on here, hoover up fast rough.
i just get the impression that the same people that dont like them wont get on with anything else, ie wants to feel they’re moving when they hit an ant, by feel, really feel that they’re moving, whilst also removing all sensation off any possible bump, suspension doesnt do that and it wouldnt be of benefit if it did.
