So I landed a jump the other day and the rear shock compressed but took about 30 seconds to recoil. After messing around with it for a while I jumped it again and it started recoiling properly again, but after a few hours of riding it went back to recoiling very slowly. So is rebuilding an option or would it just be cheaper to buy one for $99 on ebay? Also what could have happened internally for something like this to happen. btw its a fox shock with piggy-back reservoir.
