Moulton NS Double Pylon

The Moulton NS Double Pylon is the most structurally concentrated model of the New Series, the separable spaceframe line that Moulton introduced in 1998. Built entirely from aerospace-grade stainless steel and hand polished to a mirror finish, it replaces both the conventional seat tube and head tube with fabricated stainless pylons, so that every principal load path runs through a dense lattice of small-diameter tubes joined by silver brazing. It keeps the unified rear fork, Hydrolastic rear suspension and Flexitor front suspension of the New Series, on 20 inch 406 mm wheels, with a quoted weight of 10.1 kilograms. Wikipedia's account of the Moulton bicycle notes that in the Double Pylon all large diameter tubes have been eliminated, leaving a pure space frame of low weight. The maker lists it as a hand-built road and race machine with a current lead time of eight to ten months.
