I’ve just built a cheapo one up. Got a Kona Fire Mountain frame for £45 and had some brakes and cranks sat on the bench doing nothing. Did splash out on a carbon fork as I thought it was the best place to put some money. When I say splash, out they were £100.
Holy sh*t it builds into a light, fast(accelerating) and agile bike. The first thing I noticed when going for a ride was how much more you sit up and look around the countryside. Thinking about your bike less and which gear to be in, travelling slower all equates to looking up and around more. I even found a couple of trail entrances in the woods I had ridden past before.
Enjoying it so far, although early days, seems to get back to why I starting biking, fast, simple, light bike to get you into the country and soak it up.
