I've not seen much Trek stuff in in these forums... I'll have to post some pics of my Y-33 soon.
I worked in a shop around the time of this catalogue and seeing this stuff reminds me of the 970 I had back then. It was a really nice bike - sold it to the son of a colleague who still has it. I put feelers out every year or so to see if he'd sell it back to me - might do that again later today. My boss had a 9800... I was just blown away by how light that frame was!
