Hi, can anyone tell me if it's possible to swap out the air spring for a coil in a dual air pike.
Cheers

    Well, i love the air as you can adjust it to what you riding in a flash but, the negative air keeps losing. I have had it serviced by tf tuned and cant fault them at all. I do my lower leg services myself but i just don't find the negative chamber holds long enough between services , the positive has always been fine. If i can whack a coil in that may be the cheaper option and the more consistent

    You can - but can I ask how you can tell the -ve air is losing pressure? Everytime you attach a pump, it loses most its air, generally.

    Yes you are right with what you say. Everytime you re-attach your pump your negative chamber will lose some air into the hose to give you a pressure reading. After experimenting (around 10 times) with a freshly pumped fork, i am consistantly losing 40 psi every time i re-attach the pump e.g pump to 130psi take off pump re-attach now 90psi.
    After a ride or even during (when i notice the fork getting a little harsher) i can attach the pump and i can be looking at anything like 50psi or less.

    Will i need a new u-turn knob along with the coil?
