From our workshop in Boise, Idaho, Io DuPont harnesses high-tech materials and innovative technologies to build your next bike, string your next tennis raquet, and more. Tony DuPont, our founder and lead engineer, is a consummate problem solver. After years of debate and speculation about synthetic fiber control cables, Tony finally built a set in his garage in 2004, and Power Cordz were born.

Power Cordz are the lightest and strongest brake and derailleur cables in the cycling world. Our anchors will safely carry more than 600 lbs on a 1.2mm synthetic cord. They are 75% lighter and many times stronger than the steel cables they replace. And they improve performance through lower friction and a higher modulus of elasticity (translation: they don’t stretch out and don’t require readjustment). Power Cordz have been sold internationally since 2005 and are available through distributors that reach every major cycling market in the world.

Tony then turned his attention to a completely new bicycle drive train called the Infinity Drive—an infinitely variable bicycle transmission. The first models will appeal to the bike racer or early adopter, looking for that competitive advantage, but we can see our IVTs becoming the new standard transmission system for the modern bicycle all over the world. It has fewer components than a derailleur system, is more intuitive to shift and will be lighter and potentially cheaper than any current options.

In 2013, Tony decided to leverage the control cables into other arenas too, starting first with packaging and offering tennis string sets that are stronger and lighter than anything else anyone else is offering.
