An advanced frame design primarily for mountain bikes that utilizes an advanced construction of lightweight tubes to create bicycle framework of greater strength without added weight. The frame design utilizes pairs of thin tubes arranged within the bike frame for increased strength and flexibility. The top tube and down tubes are of double tube construction in the invention. Bridgework tubes are smaller tubes that are used to connect portions of the various doubled tubes to one another to provide a secondary support structure for the frame.
A beyond 2000 frame design that corrects faults in road bicycles by creating a lightweight bicycle with rigid cranks and a resilient saddle. An improbable mix brought about by attaching the seat stays to the upper slope of the down tube thus enclosing the bottom bracket in a rigid triangulated box that eliminates stays to the top of the frame in a direct line of shock to the base of the spine. Resulting in this rigid yet resilient, (no hands accurate) safe bicycle that climbs effortlessly and descends as if on rails.
