So I'm planning on piecing together a single speed commuter by this summer and I was hoping you guys could give me some help with choosing the right parts. So far I have looked at the Specialized Langster and the Schwinn Cutter, but I cannot find a frame-only for either of those. If I could just have some help with choosing the right frame to order I could probably work with my local shop to get the rest of the parts. I have no experience in road bikes (I've only Mt. Biked my whole life), so any help is appreciated. Thank you.
