I found an old 1980 Nishiki road bike at the side of my inlaws' garage starting to rust and generally falling apart, so I decided to turn it into my commuter bike. I've done plenty to it over the past year such as having it powder coated red, because red bikes are faster. I bought the bar end converters to move the stem clamp-on shifters to the bar-ends. I also rebult the wheels to be 622mm rims which are smaller than the old steel couldn't-stop-in-wet-weather 630mm rims, which let me put on fatter tires.
My commute is 17 km each way mostly on MUP by the river, but I've found a dirt and rock shortcut up the hill that makes use of the 38 mm tires.
