I'm looking to either build or purchase a steel singlespeed bike that I will use to commute around 20 miles daily. I have the option of purchasing a used (mint) karate monkey in a local shop with real sweet components (thompson, brooks, salsa, BB7's) for $800-$1000 that one of the customers built up. I'm not sure I could build one cheaper or just by a SS 29er frame and build it or by a whole road bike SS. Steel frame for sure even though I'll ride it throughout the winter with studded tires. I definately want a SS, any suggestions?
