Overview
Crankset Shimano GRX FC-RX820-1 (1x12-speed)
Shimano GRX FC-RX820-1 1x12-speed crankset is engineered for gravel and mixed-terrain riding, offering an ideal balance of weight savings, stiffness and gearing versatility. As part of Shimano’s gravel-specific GRX platform, it allows riders to fine-tune their drivetrain to match terrain and riding style.
Paired with a 40T or 42T chainring and either a 10-45T or 10-51T cassette, riders can choose between tighter gear steps for smooth cadence control or an ultra-wide range for steep climbs and fast cruising. The HOLLOWTECH II construction ensures efficient power transfer and high stiffness under load.
A 49.7 mm chainline and 151 mm Q-factor are optimised for wider tyres and gravel frame geometry, delivering stability and control on rough surfaces. The 4-arm 110 mm BCD design and compatibility with HG 12-speed chains make the FC-RX820-1 a reliable and versatile choice for racing and adventure riding alike.
