The last time I was in Mellow Johnnys in Austin, which was at least 5 years ago, there were a number of his retired race bikes on display.
I recall seeing one of the Motorola bikes and a few of the Trek bikes. I also think the rebadged Litespeed Sabre was on display as well.
Regardless of your feelings towards the man, his racing career spanned an interesting time in product development for the cycling industry; the same can be said for the PED time period as well.
