Help, broken fixed cog?

hey,
if you still have the free wheel on the other side of the hub then you could flip your wheel (put brake back on) and ride to w1. i work on wardour st and would be happy to sort out your wheel, show you how to do it your self next time and tell you which tools you'll need. just let me know.

obviously you could just ride to your LBS as well.

I suddenly feel very silly, you are completely right, PM is on its way about offer for help.
