Shimano Road FC-RS345 Crankset 50-34T 2x9V 175 mm Octalink

This FC-RS345 road crankset from Shimano is designed for 2x9-speed road drivetrains using an Octalink bottom bracket interface. The compact 50/34T chainring combination provides novice and recreational road riders with a perfect blend of higher-speed gearing and easier climbing gears. Shimano HYPERDRIVE SG-X chainrings ensure smooth and reliable front shifting, while the 175 mm crank arm length, 110 mm BCD, and 5-arm construction make it an ideal replacement crankset for compatible Sora 3500 Series setups. Please note that the bottom bracket is not included, so be sure to select the correct Octalink unit, such as BB-ES300, separately.
