A 1987 Jamis Explorer that my Dad passed down to me in about 1994 when I was 13. I still have it. It’s survived my middle school, high school, and college years (including two years in the dormitory bike room, which was a glorified maintenance storage room, getting crushed by other bikes). I’m in the process of fixing it up to become a neighborhood cruiser / campground bike. It has a steel frame, 26-inch tires, a gel saddle, cantilever brakes, one aluminum rim, one steel rim, rear rack, bar ends, a kick stand, and a bell.
It probably doesn’t make sense to be fixing it up, but it has some sentimental value to me.
