Grubb Screw on Campag Freehub Body-Why?
On freehubs over a certain age (pre 2002ish?) there is a grubb screw on one of the splines. It appears to neither retain the freehub in position or serve any other obvious purpose. Am I missing something by never doing anything with it?
Greetings from the wet and windy North west
