Replacement Bolt for Cinelli Stem?
 

I've found a 100mm Cinelli stem for my Bianchi Trofeo, but the bolt is pretty rusted - still usable with some sanding, but needs to be replaced. Is there a source for replacement bolts, or failing that, what are the dimensions and thread size?

Thanks!

i always hit the local shop and just test fit with the large amount of extra bolts from various stems and equivalent parts they have. and its free pretty much.

It's a standard diameter and threading. There is some variation in the diameter of the bolt head, but I suspect the size you need is the one that is most common. They're available via your LBS, on eBay or online retailers.
