Stock wheels. They do feel heavy and slow. I see that there are 3 wheel sets in the Sirrus line. Axis Classic, Axis 2 on expert model, and Axis 4 on pro version. Just bought upgraded wheels and tires. Vuelta Corsa Disc lites are on the way. Also got Continental Grand Prix 4000 II S tires. Changing from 30mm wide stock tire to 28mm. Hoping to get greater efficiency, while maintaining comfort. Will submit new photo when completed.
