From 509 Cycles Website!
We are super happy to announce a new bike in the line up for us, The Necessary Evil. About two years of development and a few prototypes later, we got a bike that is fully capable from road racing to hitting single track and anything in between. Like our Jabit III frame, we wanted a bike that was extremely versatile and could be build up several different ways. We also like the option to have two sets of wheels for this bike, just 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.
The Necessary Evil is offered in 5 different sizes (50cm,53cm,55cm,57cm and 59cm) along with your choice of stainless steel or titanium. Keeping the bike simple but fully functional was our main goal on this bike. We stayed with an English threaded bottom bracket, 27.2 seat post, fender/rack mounts, easy to maintain external cable guides, flat mount disc brakes, thru axle and a 44mm head tube for straight or tapered steer tubes. Along with those key features, we wanted the ability to use all three water bottle mounts when using a frame bag like the Revelate Designs Tangle.
