Arctos Jigs are simple, rock solid tools for making the world’s finest bicycle frames. Originally designed by Gary Helfrich more than 20 years ago, Arctos Jigs are handmade in Portland, Oregon by veteran machinist and framebuilder Oscar Camarena.

Our Jigs are manufactured to the tightest tolerences from the best materials in existence. They are used by some of the most demanding customers in the bicycle industry – Chris King, The United Bicycle Institute, Soulcraft, Co-Motion, just to name a few.

Whether you’re a hobbyist or a professional frame builder, the Arctos Jig is the last frame fixture you will ever need.
