Its actually called a "stayer" stem, used in motorpacing. Not sure they used em on traditional track bikes, but it was too cool not to use. I got the bike pretty rough, someone had converted it to a roadbike by crudely brazing on a derailler hanger, adding clinchers and drilling for brakes from and rear. Brian Baylis did the repairs and fantastic paint, stripping and decals. Just to be different I used some wood rims. The Brooks was handcut into a swallow like my stepfather showed me how they did em in the 50s. Thanks!
