i finally fully committed to fixed only by removing my freewheel from the other side of my hub. my main concern is that normal wear and tear (i commute and go on occasional rides through the city) can damage these threads (i might want to put the freewheel back on in the future- ya never know, i like options). also, the shiny fresh threads just look out of place on my otherwise all black bike. i was thinking of maybe getting a bmx-style hub guard or maybe fabricating something like a small thread on sleeve. has anyone else ever addressed a "not-really-an-issue" like this before?
