Shimano GRX FC-RX820 1x Crankset

The Shimano GRX FC-RX820 1x Crankset is built for gravel riders who want strong performance and smooth handling across different terrain. It uses a single 40T chainring and works with Shimano’s 12-speed drivetrains, giving you the power and control you need for both steep climbs and fast descents. Whether you're racing or exploring, this crankset delivers reliable shifting and improved efficiency.

Thanks to its Hollowtech II crank arms, the FC-RX820-1 is both strong and lightweight, helping you ride longer without extra strain. The 49.7mm chainline and wide Q-factor give better tire clearance and stability on rough roads. With options to pair the crank with either a 10-45T or 10-51T cassette, you can choose tighter gear steps or a wider range to match your riding style.

Key Features:

• Single 40T Chainring – Simple and reliable gearing for mixed-terrain adventures.

• Hollowtech II Arms – Lightweight yet strong for efficient power transfer.

• Custom Gear Range – Pair with 10-45T or 10-51T cassette for climbs or speed.
