Compatibility
Shimano GRX RX820 Groupset is a Shimano groupset. It is a 12-speed component. It uses Cable shifting. Everything listed below was matched on a specification we hold for both parts: the interface each pairing actually depends on, such as freehub body, speed count, actuation or mounting standard. Where we could not verify that interface, the part is left out rather than assumed to fit.

Frequently Asked Questions
What fits Shimano GRX RX820 Groupset?
On this page we list wheels with a freehub this groupset fits. Each listing was matched on a specification we hold for both parts; anything we could not verify is omitted rather than assumed to fit.
Does Shimano GRX RX820 Groupset work with electronic shifting like Di2 or AXS?
No. Shimano GRX RX820 Groupset is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
Is Shimano GRX RX820 Groupset compatible with rim brakes?
No. Shimano GRX RX820 Groupset is built for disc systems. The mounting standards and wheel/frame interfaces for disc brakes are different and cannot be mixed.
