I'm looking to put a front brake on my fixed gear for safety purposes. However, my front wheel happens to be a non-machined Deep-V. I'm aware that doing this will wear the surface away anyhow, but was wondering if any local bike shops are able to machine sidewalls? Is this something I could do myself with really really fine grit sandpaper? I know that sounds like a bad idea. But all I've been able to find online is this DIY instruction for bicycle brake resurfacing here..
..but am not sure how different RE-surfacing is than the initial surfacing.
Who knows. Anyway, I'd rather not buy another front wheel, and don't mind looking ghetto, so if no one knows of anything I guess I'll just deal with it.
