I just went and checked out this mountain bike and know nothing about the frame maker. Viri??? I was wondering how much I should offer the guy. He wants $600 for it but that seems way too high. And I can't find any info on it online. It's in good condition but needs a tune up and pedals and wheels need truing. It fits me I think. I couldn't ride it with flats and no pedals. Any help would be great. Thanks! Heres a link to the add.
