I'm looking into adding a dynamo soon and have been looking at a compatible headlight for the new setup. My fork has a threaded hole in the yoke in the back (fender is attached to it now) but none in the front. I'm also switching out the brakes from the cantilever brakes and will have the exposed bosses left on the forks. Can a headlight be directly bolted to one of the empty bosses? I've been looking at the supernova e3 pro 2 and I'm hoping the mount that comes with it will bolt right up with probably a different size bolt.
