So I have this old Mongoose Rockadile.. thing must be 10-12 years old but I love it and it's treated me well. I've been dabbling with the idea as of late to replace the fork with front suspension. Obvious problems are that its threaded and has cantilever brakes. I'm wondering if anyone has experience with a similar mtb makeover. I'm looking at coil based f.suspension with about 80-100mm of give. I do mostly XC type biking as well as some road with it. I've been looking at replacing it with threaded, or swapping out more parts and going unthreaded. Looking for some insight or opinions in the matter. I'm not interested in purchasing a new bike at this time, so keeping to said topic would be appreciated. Thanks!
