Yes i know.
It is a Mongoose Iboc Signature.
The front end is made of Titanium (by Merlin), and the rear end is made of steel (By Fat Chance?). It is a very rare to find bike.
I have oned a Mongoose Iboc Signature 20 inch.
But i sold it because it was to big for me.
If you are interested in this frame than give me a pm, so i can contact the current owner to ask him if he wants to sell it.
