Building up my new single speed bike, looking for a decent wide based ss cog, that hasn't been made wonky like my old superstar one is! I've seen CTBM selling the WTB LaserDisc cog, but that looks to be from the same factory as the Superstar one...
So, what are you using, and most importantly is it central and not on the wonk!!
Any one tried the Niner Cogalicious? Looks to be well made and suitably blingy.
