Plus One Lap:

it started with looking at the design for the Empella Frogglegg brakes as well as the Paul’s Neo Retros. I knew I wanted them to use V brake style pads (as opposed to the smooth post style pads that are used on the Empella brakes). The primary reason I wanted to go with V style brakes was so that I could toe in the brake pads for better adjustability as well as I thought making arms to accept the V style pads would be easier to make. My first try at making a cantilever arm came out really bad. I simply

laid carbon over a thin plywood board (8mm in width). Unfortunately, the width of the board wasnt enough space to fit a V brake pad nut into. I realized, that the area where the brake pad mounts to the arm had to be wide enough to accept a V brake pad nut (13mm) but the brake itself down where it slides onto the stud needed to be narrower (8mm) in order for the empella straddle nut to slide in place.

Back to the drawing board….
