The GRX FC-RX820 crankset was developed to perfectly combine performance and versatility in the gravel sector. With its HOLLOWTECH II aluminum crank arms, it offers an excellent stiffness-to-weight ratio. The 2.5 mm wider chain line allows for greater tire clearance and optimized frame compatibility, ideal for demanding terrain.
Specially designed for 1x12-speed drive systems, this crank offers flexible gear options for different riding styles. With two chainring sizes (40 or 42 teeth), it adapts perfectly to the individual requirements of gravel riders - whether for narrow gear ratios or maximum bandwidth.
