Description
The SHIMANO FC-RX820-1 crankset offers a balance between weight savings, optimized efficiency and a range of gearing options to meet the different demands of mixed terrain riding. By combining a 10-45T or 10-51T cassette with a 40T and 42T chainring, a narrower gear gradation or maximum bandwidth can be selected as required. The FC-RX820-1 is available in crank arm lengths of 170, 172.5 and 175 mm and thus offers a further option for individual customization.
