I have a Mount Vision (2005) with a WTB headset which needs new bearings. I’ve tried several on line shops as well as my local shops, but no one seems to have any.
I’ve also looked at bearing suppliers who have the right size bearings but not with the correct taper.

Anyone have any ideas where I can get some ?

give these a try, I have found them very helpfull

google them and you will find them

Possibly not a lot of help, but when mine wore out, I replaced with an FSA orbit 11, used these before and they last ages. When the bearings finally go you just replace the cartridges, and you can get spares for these anywhere.
