About us

My name is Jeff Jones. I'm a cyclist committed to the non-suspended bicycle. My ideas and passion have created an exceptional ride - a trail-blazing geometry that delivers superb handling, comfort and efficiency. My bikes are available in titanium and steel, to be ridden off-road (and on) for exploring and racing, adventures and fun. They are outrageously responsive bicycles - frame and forks designed in harmony to provide a rigid bicycle that is anything but. A pure cycling experience like no other.
