I had a 1990 +/- GT Karakoram rigid frame that I bought new back then and rode a fair amount. It is in near pristine condition because I overhauled it on a regular basis. I gave it to my older Son and we put some 26 x 1.9 smooth tires on it and he uses it as an urban cruiser in the city where he lives. He told me he is loving it. That makes me happy. I will see if I can get him to email me a picture of it, so I can post it.
