Got a 2011 giant trance x4, was adjusting the rear shock today as the bike had been unused for about 6 months, it takes air ok and holds it as long as the pump is screwed in but as soon as you unscrew the pump it dumps all the air out the valve - is it a sticky valve and is it repairable - it's a giant own brand shock. ta in advance
Giant trance shock air woes
Sounds like the valve core is loose. It's a schraeder valve so you can get a core remover/fitter
