The 1st FG that I rode was my coach's pre-WWII track bike, this was like the bike that I raced back when:
A good solid machine for it's day.
Had the fork drilled for a brake to use it for winter FG base miles where it rode like a lumber wagon, was nervous in cross winds and decidedly twitchy descending at pace on the road. Oddly enough the environment of the Velodrome is unlike that of the open public roads and a machine designed for one may not be suitable for the other.
Been riding road bikes converted to FG for the last several decades, works for me.
