Of all the various US made CNC-art-object derailleurs of the mid 1990’s the Precision Billet Proshift seemed to me to offer the most. They were devastatingly light, had two sprung pivots (and so were widely considered to work with Shimano SIS) and had all the trick elements; stainless steel fittings, sealed bearing pulley wheels etc.. Precision Billet also seemed to be a serious company intent on actually manufacturing hardware rather than vapourware.
