'91 Trek 6000 Sizes
This is for sale about an hour away and I've been trying to work with the seller on figuring out the frame size, they're saying the seat tube measures 13"!? I don't see that size listed in the '91 catalog, did they make them that small?

Not a 13", it's a 15" most likely.
Trek listed 15" as the smallest size for the 1991 6000. The smallest size for the entire MTB line that year was 14.5" for the steel models.

Based on the picture, I would say that's a 15". 26x2 tires are just under 26" in diameter, and if you compare the hub to tread distance (radius) to the seat tube, the seat tube is longer than 13". (26/2 = 13)
This is what a 13" looks like. The seat stays line up with the down tube:

Thanks for confirming, it looked like a 15" to me, but didn't want to drive an hour+ each way just to find out I was wrong
