509 Cycles Necessary Evil
Available in either 2205 Stainless Steel or 3/2.5 Titanium Butted Tubing.
The Necessary Evil is fully capable bike ranging from road racing to hitting single track and anything in between. Like the Jabit III frame, this bike is extremely versatile and could be build up several different ways. The option to have two set of wheels for this bike, like our fat bike. When doing long road rides it’s great to have a set of 700 wheels but when you want to get off the pavement and hit some gravel, fire roads or adventuring into the unknown a set of 650b wheels is very accommodating. The Necessary Evil can fit up to a 700x47c or 650×2.25 tire in the frame, this is due to the CNC machined yoke that we use. The center of the yoke is drilled out to save weight, but has plenty of material to keep the frame stiff and strong with a large welding surface.
