Steel 29er SS/Geared

There's a few different ways to build a single speed and this is the version with Paragon 'Rocker' dropouts. The other two methods are EBB or Paragon 'Slider'dropouts. The rockers are maybe the most economical and clean looking style so that's what I used on this build as this frame might wind up being my own bike.
I also used a head tube that will take an integrated drop-in headset. This is the style I use on nearly all my aluminum frames but rarely use on steel. The advantage of this style is that headset bearing replacement is easier and the head tube winds up being a bit longer - this works well on bikes like this where the tubing is fairly large diameter and head tubes are usually short enough to make a small landing place for the top and down tube to be welded to. Frequently the top and down tube will overlap, creating a more difficult mitering and fit-up situation. 
This frame also has internal dropper post routing. The rocker dropouts are angled such that the rear brake is down tube routed rather than top tube routed. There are several inserts available for the rockers so that post,IS or even flat mount brakes will fit. The rocker dropout is usually a $ 130 upgrade on the stock steel frame price.
