For Gilco and Trafiltubi's 2006 and 2007 anniversaries, Trafiltubi presented two commemorative frames created by Simoncini Telai in limited edition and from an exclusive Gilco design.
Both these frames are available in two high-tech materials, 15CDV6 and HInoxTUBE®.
The latter material is used solely in the ORIGINAL GILCO FRAMES, not withstanding the exclusive rights conceded by Trafiltubi to Columbus for use with bicycles.
The Gilco frames are produced in two design versions:
the Dual 60G, that celebrates Gilco's sixtieth anniversary,
and the Dual 40T, dedicated on the other hand to Trafiltubi's fortieth birthday.
Both models develop the original Gilberto Colombo idea of a double piping frame, that was created in the Forties in an original round version (the "boat" or "cradle" frame) and that, after further development, took on the form of the Dual in 1987
