This is a frame I wanted to make with a standard bottom bracket shell and slotted dropouts and standard seat post.
This would have been an entry level Rumblefish and a 2nd model.
True temper Chromoly main tube. Wishbone seat stays and aero tubing front struts.
I made a Rumblefish fork, Rumblefish handlebar/stem combo and Rumblefish cranks.
Browning 2 speed, spin wheels.
