The Shimano GRX FC-RX610-1 crankset is built for riders who move seamlessly between tarmac, gravel and rough backroads. It balances low weight with efficient power transfer to handle changing surfaces with confidence. This is a dependable 1x crankset made for real-world riding.
Efficient 1x Drivetrain Design: Designed around a 1x12-speed setup, the FC-RX610-1 keeps shifting simple and reliable. Fewer components mean less maintenance and cleaner performance in dusty or muddy conditions. Ideal for gravel and adventure-focused riders.
Flexible Cassette Pairing: This crankset pairs easily with both 10–45T and 10–51T cassettes. Riders can choose tighter gear steps for faster rides or a wider range for steep climbs. It adapts to different riding styles and terrain demands.
38T and 40T Chainring Options: Available with 38T and 40T chainrings, the FC-RX610-1 allows riders to fine-tune cadence and top-end speed. These options make it easy to tailor the drivetrain to fitness level and route profile. A practical choice for mixed-surface adventures.
With crank lengths ranging from 165 mm to 175 mm, the FC-RX610-1 supports precise bike fitting. It delivers smooth, efficient pedalling over long distances.
