I currently have my mountain bike disassembled, I broke a tire and needed some space in my room. The frame is resting upside down on the saddle and handlebar.
The fork itself is a Rock Shox SID Dual Air (pretty old model, I guess 2001). As this fork relies - to my best knowledge - only on air, storing it upside down shouldn't be a problem. Am I correct, what about other types of suspension forks?
