I came across this Maserati that I forgot I had. The steel has a nice "ring" to it but it may be just another Italian sweatshop frame. I also had a pair of Ritchey tires that have a cool cyclocross vibe to them. I would like to build a 3sp Urban Assault bike since I haven't had a skinny wheeled bike in years. One thing I am really concerned about is the bottom bracket threading. I looked at Sheldon Brown's web site and didn't find anything regarding thread specs. Does anyone have any ideas about the BB?

I was just on the Park Tool page earlier looking at the specs on my French bottom bracket. The Italian specs are there too:

"The Italian Standard uses a threading of 36 mm x 24 threads per inch. Both sides of the bottom bracket are right hand threaded. Parts in the Italian standard are usually marked as such. Not all Italian-made bikes use Italian Standard threading. Frames in this standard can be distinguished by a 35 mm inside diameter."

Just saw a new sealed Italian BB at Velo Orange, $30. Don't know if this will help, but it's out there anyways:

Or you could use one of these repair BBs. These are supposed to fit most BB shells and don't use the threads.

Wow, thanx, Pondo! I would not have thought to look at the Park tool catalog! I have been calling around to several LBS for either of theses BBs and the responses have been laughter or dead silence...:crazy2:

So, the above info gives me some options depending on the lead time I'll need to receive parts. If this doesn't work, I have a few of the standard BBs and I should be able to come up with a different frame......
