Pro Neck BMX company started in the very early 80’s, I think it was 1981. They only had stems the first year then the product line expanded with Framesets, Handlebars, Seatposts and Number Plates. Flash forward a couple years and they had chainrings, chainwheels, power discs, seat post clamps ( SPC ) padsets and clothing. I most likely missed something and that timeline is probably not entirely accurate.
This Pro Neck Gooseneck is a mid 1980’s Old School BMX part. The original finish was in very rough shape so I decided to sand and polish the stem. I can’t remember what color it was originally, sorry. Bolts were rusted and rounded out so they were replaced with stainless steel allen bolts. Normally I would not have removed the original finish if it had been savable. Unfortunately the anodizing was destroyed and it had lots of gouges and tool marks. It’s almost a mirror polish, the pictures do it justice for the most part. Somewhere along the line I misplaced the wedge and wedge bolt. You can find replacement hardware for these vintage stems. Some wedges are notched, some angle cut.
