Shimano GRX RX820 1x Crankset Info

The Shimano GRX RX820 1x Crankset is built for gravel riders who want a clean, single-ring drivetrain without compromising on power transfer or durability. Hollowtech II arm construction keeps the crank arms stiff where it matters — out of the saddle on a loose climb, or pushing through the pedals on a long mixed-terrain effort — while holding weight down relative to a solid-arm design.

Two chainring sizes, 40t and 42t, pair with either a 10-45T or 10-51T cassette, giving you the flexibility to tailor your gear range to the terrain you ride most. Three crank lengths — 170mm, 172.5mm, and 175mm — mean you can dial in a fit that works with your pedalling mechanics rather than adapting to whatever's on the shelf. At RX820 spec, this sits at the upper tier of the GRX family, bringing a level of finish and refinement you feel in every pedal stroke.
