Good condition and a working vintage RockShox SID dual air fork long travel in iconic blue, needs nothing. Steer tube is 1 1/8" 7.5" so will fit small and medium frames. Everything is in good condition, some paint chips as expected for a 25 year old fork. I think this is a 2nd gen SID based on the small arch and disc mount. This will need a SID specific adaptor to add air but likely you already know that. Lightest of the early suspension fork in the late 90's.
