Porsche bike s is a superbly built, lightweight hardtail that tackles mountains with an amazing battery of technologies. Start with its rigid triangulated frame of ultralight 7020 alloy aluminum, built around a 60mm main tube for stiffness and control. Add a motorcycle-style suspension fork for a smooth ride. Then bolt on the shimano rapid fire shifters for quick shifts on the go, plus magura hydraulic brakes for an astounding level of stop. And don 't forget the shimano lx gearing that allows for smooth, rapid shifts (up to three shifts per stroke) even under a full load. The final result: a two-wheeled machine that 's worthy of the name Porsche. Made in Germany.
