From the seller:
Made in College Park, MD, this is one of the finer examples from one of the Mid-Atlantic’s better known shops. Proteus is still a bike shop, but in the 70s and later it was also known for the Proteus frames built in-house, frame-building kits, and The Book on frame-building for amateurs.
This is an extremely well-preserved, first-class, vintage criterium bike – note the angles and wheel base. It is a wonderfully responsive bike, but not squirrelly.
I fell in love with it for what is, but I’m getting older, and my interests are shifting away from these criterium bikes toward classic touring and long-duration road bikes that emphasize comfort over ultimate performance. So, this bike needs a new home. Will ship within continental USA, and can negotiate parts change-outs or sale of frame-set alone.
