Shimano FC-RX820-1 12-speed gravel bike crankset

Shimano offers the FC-RX820-1 Gravel crankset to achieve significant weight savings compared to a double chainring setup. Efficiency is nonetheless optimised thanks to the range of gear options available to meet the demands of Gravel riding, which combines roads and trails.

The Shimano FC-RX820-1 crankset can be paired with a 10-45T or 10-51T cassette, allowing cyclists to choose between closer gear ratios or a wider range. Available with 40- and 42-tooth chainrings, the FC-RX820-1 crankset is offered in three crank arm lengths – 170, 172.5 and 175 mm – to provide an additional level of customisation.
