Paragon Machine Works – A Thirty Year Retrospective

In May of 2013 it will be 30 years since Mark Norstad founded Paragon Machine Works, and began making bicycle frame building components on a manual milling machine in his home basement.  During this time, bicycling has changed from a fringe activity to a wildly popular sport.  People now appreciate the value and artistry of a hand built custom bicycle frame.  Paragon Machine Works is proud to have been an integral part of this evolution.  We have grown from having a parts list that fit on one type-written page (if you can remember what a typewriter was), to manufacturing a wide variety of bicycle frame building components in titanium, steel, stainless steel, and aluminum.  The bicycle industry is dynamic and demands innovation.  With input from frame builders around the world, we work to create new products and improve our existing ones.  This year at NAHBS we will debut our latest dropout, the PolyDrop, along with a variety of our components.  Our knowledgeable staff will be on hand to answer questions, and share in your enthusiasm for finely crafted, hand built bicycles made in the USA.  To see our full product line visit our website at

Exhibitor News:
Paragon Machine Works PolyDrop:

We are excited to debut our new low mount dropout, the PolyDrop, at the North American Hand Built Bicycle Show. It will be available for general sale in limited configurations by March 1, 2013.  The PolyDrop is a dropout assembly that includes two seat stay components, two chainstay components, two aluminum inserts, and ten cap screws.  The dropout pieces are available in 6/4 titanium or 17/4 stainless steel. The angle of the seatstay tabs are 44 degrees, and may be cut back by the builder to accommodate larger angles.The interchangeable inserts are machined from 6061 aluminum and allow for almost any configuration of axle, hub, and brake. Inserts available for sale in March allow for two configurations: a 10 mm axle with an ISO brake mount and a conventional derailleur hanger; and a 142 x 12 hub with a 160 post mount and Shimano direct-mount derailleur hanger. Ten black zinc-plated M5 x .5 oval-head cap screws (five per side) hold the inserts in position. Inserts that allow different configurations will be driven by market demand and will become available over the coming year.
