Thanks for putting that up, John.
I had that same bike - except with a Mike Augspurger One-Off Ti fork instead of the Yeti Accutrax - and raced in '90 and '91.
Not aware,of too many photos of Tomac on his all titanium, Merlin-built Mongoose since he switched to Yeti - first on a FRO then a C-26 shortly thereafter.
