Shimano GRX RX820 2x12 Mechanical Groupset

Description

Undroppable On Any Surface

For riders seeking the best of both worlds, the Shimano GRX RX820 2x12 Groupset delivers an ultra-wide gear range for spinning a comfortable cadence when cruising the flats, smashing endless dirt road rollers, or tackling a massive backcountry climb.

This drivetrain delivers precise mechanical front and rear shifting and features integrated SHADOW RD+chain stabilizer for ultimate drivetrain security over bumpy terrain. It maintains tighter rear cassette gear steps, ideal for subtle cadence changes during competitive racing and spirited weekend group rides. And the 2x12 setup seamlessly interfaces with most existing 700c wheels thanks to its use of the tried-and-true HG freehub body design.
