This '86 Diamondback Ascent was a great cruiser although a bit heavy.
This '93 Diamondback Sorrento was purchased for my younger son. Picked it up for $50 as it needed a bit of work. Spent a few hours lubing and adjusting then took it for a test ride. While I rode around, I was trying to figure how I could keep this bike for myself. Really light frame but also very stiff. Even with the stock 200GS components, it shifts as smoothly as my Ultegra-equipped road bike. I have been trying to find one for myself every since.
