Shimano Claris FC 2450 46x34t 8 Speed Crankset Black. Breathe new life into that beloved road, cyclocross, or touring rig that still sports a 2x8 speed drivetrain courtesy of the Shimano Claris FC 2450 crankset. Blasting down descents or muscling huge gears on flat terrain isn't everyone's cup of tea and the compact 4634t chainring combo serves up a perfect slice of knee saving heaven. Spin up the steepest climbs without busting a lung on the 34t inner ring while still enjoying some respectable top end speed when necessary on the 46t outer ring. As is the norm with Shimano cranksets, shifting between the 'rings is smooth and precise while the overall package is incredibly reliable and long lasting.
