I know the whole point of the Firefly Bones project is to offer a unique *steel* frame, made in Boston and hand illustrated by Eric Bones, but I can’t help but think these are the best looking collaboration bikes to come from a frame builder and I’d love to see them go into full-scale, mass production.

Each of these builds have unique details as well. What caught my eye here was that titanium stem and the proportions of those Dura Ace cranks. This bike looks mean.
