What are you looking for in a Frame? Material? Tire Clearance? Do you have a purpose in mind like CX or MTB or just a track bike or SS/FG road bike? Are you looking for something more custom or just a stock frame? Budget?... I could ask a billion questions but you need to come at us with a here's what I am looking for.

You could also tell us what you like and dislike about your current bike and if you are looking to upgrade or add a bike (n+1 is important). Give us some base other than a single speed

For me I am looking to build up a fixed gear road bike with clearance for 700x32 with a lightweight steel frame w/track ends and full carbon 1 1/8 straight steerer fork. I am running brakes front and rear most likely eeBrakes with some form of aero/basebar. No need for rack mounts but two bottle cage mounts. This would give someone a platform to tell me I am looking for this frame or that frame. Granted in this situation I kind of know what I want but three other bikes have gotten in the way and so I don't need much advice now.
