I only used these wheels during fixed gear races. The wheels haven't been used much and are in good condition. These wheels have Continental Competition tubular tires. The width of the tires is 25 mm. Miche 15t sprocket included. Can be used on a velodrome or in fixed gear races on the street. Less suitable for commuting. The measurements of the hubs are: 9x100mm (front), 10x120mm (rear).
