Shimano's newly developed Sora is designed for a wide range of riders, offering robustness, affordability, and flexible solutions. Both beginners and experienced cyclists will appreciate the comfortable 9-speed group on their road bike, fitness bike, or urban bike. To ensure top-notch performance, the new Sora incorporates many technologies from the high-end groups. The black-gray finish of the components has also been adopted, providing an elegant and high-quality appearance. This stylish 3-piece crankset, with its chain guard ring, is particularly suitable for sporty city bikes. The stiff 2-piece construction ensures optimal power transfer. The large chainring made of aluminum/resin and the smaller steel chainrings provide long durability and precise shifting.
