Rock shox sid dual crown 26 9.25 x 1 1/8. Item performs as it should.
Item has always been nitrogen charged and has held pressure for 10 + years. Originally was 100 mm of travel but I have installed a spacer to drop it down to 80mm that can easily be removed. Uncertain of its internals but feels silky smooth. Upper tubes are super clean. A few scratch marks between the two crowns visible in photos.
There are a few paint bubbles on the rear of both lower legs viewable in photos. There is a star nut in the bottom of the steer tube for a fender mount. The rubber frame bumpers have a bit of dry rot. Original additional upper crown is included. The fork has less than 150 miles on it at the most.
