Removed from my wife's new bike unused as she requires shorter cranks. You can see from the threads that pedals have never been fitted. A few small chips to the paint on the teeth where the chain was resting during delivery. The Shimano GRX FC-RX600 170mm Crankset is a high-quality and durable component designed for gravel bikes. Made from aluminium, this double chainring crankset features a sleek black finish that adds style to your bike. With 2 speeds and a part length of 170mm, this crankset is compatible with Shimano brand components and is a great choice for enhancing your cycling experience.
