Motor Paced Stayer Frame

A Mysterious Motor Paced Stayer Frame – New Arrival

Every now and then I spot something slightly different, something that I struggle to identify but which has the potential to be something nice, maybe even special. Usually I might be the only one to spot it which normally gives me the luxury of a little time to do some research. On this occasion though, several others had also spotted the same frame, so with a growing queue of people forming and all asking me questions about it, I had to commit on a hunch and buy it.

You probably think seat stays are quite boring, why on earth would I devote a blog post to the two narrow tapering tubes on the back of a frame? Well as you hopefully all know by now, I do like my details, especially the small details! The various designs and subtle differences in seat stays can tell me a lot about an SBDU frame, even the frame age and tubing type.
