Sorry for my ignorance but... Why not just by a standard freewheel and put it on a flip flop track hub where you could even have two freewheels?
A question answered (albeit with another question) right at the top of Profile's product page;
*"Have a track frame you want to make into a single speed, and really hate freewheels?"
*I've been running a traditional 120mm SS setup (Shimano SF-MX30 on Formula Double Track hub) for only a few weeks now, and can already see why anyone who rides SS full-time might want something that doesn't sound like two midgets engaged in a ping-pong rally inside their freewheel. When I coast, it's smooth, silent and really fast. When I pedal, I wonder what the fuck's going on in there.
WI Freewheels are great if you're absolutely sure what size you want. For the rest of us, the arrival of a cassette SS hub is just common sense.
