Shimano's newly developed Sora is designed for a wide range of riders, thanks to its robustness, affordable pricing, 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. The sleek 2-piece compact crankset with a 50-34 gearing is particularly suitable for sporty road bikes. The stiff 2-piece construction ensures optimal power transfer. The large chainring made of aluminum/resin and the small steel chainring provide long durability and precise shifting.
