15 Minute Single Speed Conversion

My buddy Matt came out last week with his mountain bike and the intention to go single speed on the cheap.  This is what we came up with:

We were lucky to find an old exploded Shimano 600 derailer in my parts bin.

The derailer was disassembled and bent into a newly functional shape in no time; the beautiful sunny day urged us to work quickly.  Soon we had single speed.

And we rode.
