With Metrea, Shimano has created a technically high-quality, urban cycling specific group of components. Metrea was developed for cyclists who prefer advanced, yet timeless, minimalist technology; for those who are looking for fun, passion and an efficient way to get around. It offers cleverly designed comfort and suitability for everyday use. The name itself is derived from the terms "Metropolitan" and "Real". This is the key concept behind the Urban Sport category: the optimum balance between function and exclusivity, suitability for everyday use and the use of high-quality materials.An elegant, corrosion-resistant 2-piece crank guarantees reliable drive performance, while the special tooth profile of the chainrings minimises friction and noise when pedalling. With different crank options, the drive can be adapted to the respective topography or the required profile: While the double set-up with 46-32-teeth crank offers narrower gear steps to comfortably master the most varied terrain, the 42-teeth single crank impresses with its simplicity and uncompromising design. An integrated chain guard makes it possible to ride even with slightly baggier everyday clothing.
