retro Manitou Swinger 3 way adjust with spv (stable platform valve) damping dual air, both chambers hold pressure blue rebound knob moves smoothly throughout it's range this is the extent of my testing I have not serviced, test ridden or internally inspected the shock so offer no warranty whatsoever small marks to the anodising right at the bottom of the shaft, should affect use decals are tatty and could do with replacing 200mm i2i with I believe a 57mm stroke, again I haven't been able to verify full stroke travel, just assuming 57mm based on 61.5mm total shaft length
