Two 27" bikes have passed through my hands in the past couple years. I converted a Trek 520 to 700c for tire choice, including wider tires and studded tires for winter. Dumping the Helicomatic hubs was a bonus.

The other bike is a Motobecane Grand Prix mixte for my lovely wife. It will just be used around town. Never in the winter. Almost never when wet (only when caught out). A 27" set of Paselas was just what the doctor ordered.
