My 1990 Cannondale ST600 in the largest size they made of this model at the time, 25 inch (63.5cm). Got it about a year ago with all original components and have since switched out most of the components. Has 700c wheels instead of 27 inch, bumped up from 7 speed to 8 speed, early STI levers instead of downtube shifters, bars, stem, etc. Through sheer coincidence, it turns out my dad had the matching Topeak rack with their quick rack system to match the used Topeak bag I bought a few years earlier. I'm digging the ability to quickly pop the bag off when I need to lock it up somewhere and slide it back on. When I'm grocery shopping, I swap the bag out for a large set of panniers that can carry a good weeks worth of food.

It gets used to commute to and from work as well as run errands in town. This is how it looks right now at work. Despite how clean it looks, it does get ridden very regularly in conditions up to a light drizzle. If it's full on raining, I'll either walk or drive. Riding in the rain sucks and maintaining bikes with exposed drivetrains that regularly see the rain is rather annoying. One of these days I'll have something with disc brakes and an internally geared hub.
