Bought complete, and have now swapped everything but the headset, seatpost and seat off of the frame. Headset is next, but I am saving for a headset press and race setting kit along with the headset. That has been the best thing about learning the whole fixed gear, conversion, single speed buisness is the prep and work time. For all the years I rode BMX I had a set of socket and allen wrenches, and an adjustable and a rubber mallet. Now I have lots of tools, makes things easier and saves me money. How gratifying was it Tuesday night to have the Bottom bracket tool in my vice and using the frame as leverage to get the cups out. It felt great. And like it was said above if something does start to go wrong it makes it much easier to fix becasue you know how everything went together.
