Being a motorcycle fan I wanted to include some moto style into a bike frame. Whilst considering wishbone stays I figured a smallish moto conrod could possibly do the job. A lot of them, particularly modern jap ones, are pretty ugly. A few look a bit better and these Triumph ones have Triumph embossed into them and are about the right size. Cut some plugs into the base that will fit into 14mm stays, carve out most of the underside, the small end to fit the seat tube and bobs your uncle.
