Bianchi TI MTB Infos please

[Zanoli]

Hi,

I'd like to learn a bit about the Bianchi "megatubes" TI bikes from the late 90's / early 2000's.
There seem to have been several models released, how to distinguish them ?
Do you know who build these TI frames ? I read Litespeed build some road frames for Bianchi maybe some offroads too ?

Thanks

Not much informations around i guess ?
