Cinelli steel stem expander bolt
 

I have a beautiful old Cinelli steel track stem but it is missing the expander bolt -- so basically it is useless. Anyone have any suggestions on finding a replacement?
Thanks in advance!

Do you have a bike co-op in your area? And did you buy Big boss man's stem? At some of the bike co-ops in Vancouver, Canada (where i used to live) they have boxes with as many as 50-100 of these not to mention the bins of other stems that can be cannibalized... if you have such a place in your area you should be able to find a replacement, it might not be a cinelli but it's just a steel bolt with a hex head so....

Thanks, that is encouraging. I don't care it is not a Cinelli bolt, I just want to be able to use the stem. Big boss man? No, I've had this stem for quite a while, but just now need to use it.
