FSA No.9-55 headset bearing

[Handlebar]

Can any of you clever okes tell me what bearings this headset takes? Its off a Merida BigNine.

 

If you know who stocks that will also be great.

I have the FSA manual in front of me (hoping to b called clever) but I can't find a headset with that code at all. A typical FSA code looks like this: 121-0464N

 

Otherwise they're known by something like Intellaset ST or No 53CF.

 

Find some more codes and lets see what we come up with.

But as an aside, you don't need to know what headset it is. Open it up and on the side of the bearing you'll find a # number, #077 for instance. That tells us exactly what bearing it is.

Thanks Johan.

The bearings were in really bad condition and the lettering totally unreadable.

I should have just measured them when I had them out but I figured I'd find out what they were on the internet. I'm pretty sure they're the standard 1-1/8" 45/45 and 1.5" 36/45 ACBs but I know the thicknesses on these vary.
