Seven Cycles is the world’s largest manufacturer of custom, high-end bicycle frames. The Elium SLX is made from seamless, double-butted 3AL-2.5V titanium and filament wound carbon fiber. Seven describes this model: “A tale of two halves. The upper consists of a carbon seat tube, top tube, and seatstays to prevent unwanted vibrations while shaving weight. The titanium lower provides a taste of road feedback, ample power transfer, and durability where it’s needed the most.” It weighs a scant 2.6 pounds.
