FSA Headset Bearings
I have a Bianchi Impulso with a "FSA NO.8B/ZS4D 1-1/8" Semi-Integrated lower part + Integrated upper part, W/ H2166B 15mm Top cover for tapered 46mm/50mm OD Head tube" Headset.
Now try as I like I cant work out what bearings I need for it. I've asked the shop I bought it from and they suggest buying a totally new brand of headset. Any suggestions?
