Couldn't load pickup availability
The Shimano GRX-820 12s 172.5 mm crankset is designed for gravel bikes and riders looking to fit a 12-speed drivetrain from the GRX series. It is compatible with HG 12-speed chains and 10-45- or 10-51-tooth cassettes, and the BCD chainring diameter is 110 mm.
When choosing a version, consider the gearing you need: the single 40-tooth chainring is simpler, while the 48-31 double offers a wider range. The chainline is 49.7 mm and the Q-factor is 151 mm, figures that refer to the GRX series.
