When I go over a sidewalk, the marker ring on my shock goes all the way down the shock, so I think I need air.
I bought a Giant "shock pump" that supposedly goes up to 400 psi. I screwed it onto my read Fox Shock, on my 2019 Giant Trance 2. The gauge on the pump reads 0. Shouldn't it be reading some air pressure, if there was air in my shock?
Then I started giving it some pumps. It resisted quite a bit. One pump it went up to 50 psi on the gauge. 2 pumps and it went up to 100. Then I can pump all day and it won't move beyond 100.
I don't think air is actually going into the shock. Is there some trick to this? I read over the manual and it just tells me to fill it with air, but there are no specifics.
- The red thing seems to spin.
- The blue thing seems to have 3 positions: down, right and left.
- Where the pump is connected is the only place I see to make such a connection. * If I screw it SUPER tight, I read 200 psi on the gauge, but it will still not accept more air no matter how much I pump.
