Shimano GRX RX820 2x Crankset
Shimano GRX RX820 2x Crankset Info
The Shimano GRX RX820 2x Crankset is built for gravel riders who want tighter gear steps — the kind of control that matters when you're managing pace on a long mixed-surface ride or pushing hard through a gravel race. The 48x31t chainring combination sits squarely in gravel territory, giving you a usable top end without sacrificing the low gearing you need when the road tilts up.
The arms are constructed using Shimano's hollow forging process, which keeps weight down while maintaining the rigidity needed for efficient power transfer. Available in 170mm, 172.5mm, and 175mm lengths, you can dial in the fit rather than defaulting to whatever ships on a build kit. The RX820 crankset sits at the upper tier of the GRX range, and the build quality reflects that — this is a component intended to hold up across seasons of hard use.
