Shimano GRX FC-RX820-1 Crankset Description:

The Shimano GRX FC-RX820-1 Crankset brings 1x to Shimano GRX 12-speed. The 1x crankset is designed for gravel racing and fast gravel riding and, when paired with a 10-45t cassette, provides optimal gearing and gear steps to provide the best performance in gravel racing. It’s constructed with a slight narrowing, compared to past models, to accommodate a narrower 12-speed chain and promises smooth and reliable shifting. With these two applications in mind, the GRX FC-RX820-1 chainring is a high-performing and versatile part of the fast gravel world.

Features:

• Narrower teeth to accommodate a 12-speed chain width
• Pairing with a 10-45t cassette provides optimal gearing and gear steps for gravel racing and fast gravel riding
