Steel long reach caliper fork.

This one has an axle to crown length of 377 so it will work with a Shimano 650 long road caliper or something like it. I used to build lots of frames and forks with this spec before disc brakes took over. I still think that this style of bike is very useful and a great do-nearly-anything platform. I owned one for almost 20 years and rode everything from a five day bike tour to a couple of laps in a rainy cyclocross race.
