Manitou SX Carbon suspension fork for 26" wheel mountain bikes. Has rim brake posts. 8"/ 200 mm steerer tube. 1 1/8" threadless.
Perfect for your vintage build.
Crown to axle measurement is 440mm. Travel is 70mm.
Came on a lightly ridden 1999 Specialized S-works M4 hardtail. Has good rebound. Great condition for being 25 years old. See photos. There are some light scratches on it. That being said, it is a vintage piece and may need replacement parts if you're going to ride it hard.
Thanks for looking!
