A great metal horse

A really great bike which I ride for about 9 years already. I use it for 15-20 km rides 1-2 times a week, for about 7 months a year for 9 years. I always take my bike to service for full Check-up and some maintenance in the beginning of each year, and through all these years I only changed pedals and done minor fixes, so I must admit a great quality!
