Silvio V 1.0 on Air
I have installed a Firestone 2M2A air bag to replace the urethane rear spring, as my aging body wanted air bags at both ends to turn mountains into pebbles, and it does.
I am running it at 25 psi to get a full 20 mm of movement instead of the 12 mm with the Urethane spring.
the 1/8"npt to schrader valve sits 25 mm below the seat back, but at this stage I could only get a 34 mm air valve extender, so it is fitted to the shock valve so I can install the shock pump onto the air bag in the two stages.
The beauty is that when I add 25 kg of rear luggage, I just increase the air pressure to maintain the same wheel travel.
I have tried to attach a pdf file of my Autocad drawing, but the system does not like it.
