Bolt in bottom bracket Bianchi Infinito

Postby jonglins » Mon Nov 26, 2012 15:56 pm

In my Bianchi Infinito there’s missing a bolt in a cable guiding plate under the bottom bracket (see picture). I think I need a special bolt. Or is it allowed to use a parker screw.

And if a special bolt is necessary, where can I obtain it?

That bike must be brand new or you are the world champion bike cleaner! So ... can you not ask the place you bought it from for another bolt ?

They're usually a standard M4 screw, typically 8-10mm long - your LBS or hardware store should have one.
Make mine an Italian, with Campagnolo on the side..

I tried a M3 but it's to large.
Can anybody tell me what kind (diameter, length) of bolt I need instead?

I finally remembered to go out and take a look at mine. It's not a machine screw. It's a pozidriv, countersunk, self tapping screw. If you've never had one on the bike, it'll be tight the first time you put the screw in as it cuts its own thread.

I've had my 2012 bike from brand new so there's no chance that it's been bodged. The one in mine was a mild steel screw with a black coating. It was already showing a bit of corrosion so I went on the hunt for a stainless steel equivalent. It turns out I had loads of them. I've got two stainless ones waiting in an envelope for you if you want to pm me your address.
