Shimano GRX FC-RX610 2×12-speed Crank 46/30

For your riding freedom: the Gravel GRX 2×12-speed FC-RX610-2 Crank 46/30T from Shimano

Finally, for more budget conscious consumers and to allow a wider price range on complete gravel bikes, Shimano has updated its 600-series cranks and shift levers for 1×12 and 2×12 setups that utilize trickle-down technology from the original 800 series GRX component line.

Top features include textured hoods and anti-slip brake lever coating that bolsters control on rugged terrain. The new cranksets offer gearing options that specifically cater to the demands of gravel riding. The 2×12 crank is spec’d with a 46/30 chainring and is available in 165, 170, 172.5, and 175mm crank arm lengths.
