Conversions are practical, it looks like it has good drop outs so it won't be slipping all over the place and with some high quality track nuts you should be gravy. It's absolutely ridiculous for all these people to say that somehow a track frame is such a magically better choice for runnning a fixed gear. Yes, chain tensioners are sweet, but it only takes a little more vigilance to keep your chain tight.
Here's what this frame has going for it:
- easy to mount full fenders on
- it fits him
- he already owns it
- and it's just cool
- also if you're into this sort of thing, two brakes if you're running a freewheel
Conversions with nice frames can be quite a nice bike, I adore my single speed conversion.
