leweee - It's a Peugeot branded Sakae SR crank that I salvaged off an 80's Pug and a Sugino 52 tooth chainring... with an 18 tooth cog in the back the gearing is steep but not ridiculous.

She was my first Pug and my first fixed gear... we have travelled a lot of miles together and figure there are many, many more miles ahead of us.

I have "nicer" bikes but these Pugs are a sickness...
