I am determined to replace the original threaded fork (1" headtube) with an equivalent 1" threadless fork with canti-brake brazeons and lugs for lowrider panniers. I've contacted Trek directly and they were useless for obtaining dimensions on the original fork. Before I can fork shop, I understand that I need the axle-to-crown race distance and rake. These dimensions are not easy for the do-it-yourselfer to measure with any accuracy. Therefore, I am hoping someone here may have already measured a fork from a 1995 Trek 520 and could pass those dimensions on to me. Thanks!
