I bought a risse shock recently not knowing its condition, but the price reflected that. Rebound damping still works, but the shaft is heavily scored. Not sure if it holds air as I can't pump it up - valve thread seems too short for a standard shock pump to go on far enough to depress the valve and allow air in). What options do I have in terms of replacement? I was toying with the idea of having something made to allow it to fit my RTS team too. I've contacted risse directly but have had no response. Anyone know much about these shocks and what's on the inside? Are they nitrogen charged etc?
