The Fyxation Quiver: The first and last bike you'll ever need
The frame starts out as one would expect, with 4130 chromoly tubing in "a traditional double triangle design with a horizontal top tube, aero profile fork and horizontal dropouts to easily accommodate a singlespeed, fixed, or internal gear hub." But here is where it gets interesting. "The Quiver also ships with our proprietary derailleur hanger and removable cable stops so it can be built up as a geared road bike with front and rear derailleurs."
