[Sherpamustache]

That’s a 1990 Mongoose IBOC Signature, marketed after Tomac went to Yeti for a year.
Front triangle and 1/3 of chainstays are made by Merlin and are Ti.
Rear monostay, dropouts and 2/3 chainstays are steel, the tubing being Prestige.
The 1989 all Merlin Ti monostay frame is the Mongoose John Tomac Signature model.

that is . The '89 Signature JT frame is not the same as the one in the ad. Nothing to do with each other

At the beginning Merlin didn't have the capacity to build 400 frames a year for other brands. Have a look on their frame no history
The former German Mongoose importer for example had not purchased a frame. There was no market for such high-priced mountain bikes back then. That changed with the MTB boom in 1991 onwards

What happened between August 1989 and August 1990? they produced more than 3400 marks ??
