This vintage Bianchi road bike fork made by Tange is in good, used condition. The fork crown is drilled for a recessed brake caliper mounting. I don't recall exactly but think that the fork came off a bike that was roughly in the 52 - 55cm range. See photos for details and confirm measurements below.
*Steerer tube: 1" threaded
*Length from fork crown race to top of fork: ~ 148 mm
