The SHIMANO FC-RX610-1x12 speed crankset strikes a harmonious balance between weight reduction, peak efficiency, and a variety of gear choices tailored to the diverse requirements of mixed-terrain cycling. When combined with either a 10-45T or 10-51T cassette and complemented by a 38T or 40T chainring, riders have the flexibility to opt for closer gear intervals or extended range, depending on their individual preferences. With crank arm length options of 165mm, 170mm, 172.5mm, and 175mm, the FC-RX610-1 offers an added layer of personalization. Return to Top
