Title: Fiiting headsets and BB's
Post by: Jazzchimp on January 02, 2006, 09:57 PM: On my builds I always like to fit NOS headsets and BB's (mostly tange) but they always need 'fettling' as they never fit easily. I have measured with a micrometer and they are always way too big to ease on and as I don't like to hammer them because I want to keep the perfect finish of the paintwork so I end up using a dremmel to lightly skim the cups. Is this normal behaviour?

How do you guys put them in - nice and easy or by teasing with a lump hammer?

but a fettled headset on a rider could result in a snapped frame.
