'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
1" threaded headsets come in two "standards", JIS and ISO. The crown race ID for a JIS headset is 27.0 mm and and ISO is 26.4 mm. A JIS fork can be milled down to ISO diameter. I expect your Fuji is ISO as JIS was common only on older Japanese bikes. Your LBS can tell you exactly what you have.
