This is a frame of considerable historic interest, as it was the very first with this lug design. It was so named because Trevor worked it out while camped at the village of Trevone, Cornwall. Coincidentally, it could also be called Trev-One.
Note the fine detailing, such as the cable routing for the rear mech. The frame has been repainted and restored to a splendid standard. Full original documentation is extant, including Trevor's original sketches for the lug design.
