Priekinis žvaigždžių blokas Shimano ACERA FC-M3000 175MM 9-speed 40x30x22T

Shimano revamped Acera group set. Thanks to the trickle-down effect, entry level riders profit from innovations made for high end group sets. The main renovation of Acera is that there is a dedicated MTB and trekking version available. A 40-30-22T crank for MTB and a two dedicated gear combinations for trekking. Both feature mega 9 light drivetrains and have a better matching appearance.Since bigger wheel sizes also became more popular in the Acera segment, the Acera drivetrain adopted the 40-30-22 triple crank.For SQUARE bottom bracketsCrank length: 175 mmTeething: 40-30-22 (triple)Arms: 4-armFor 9-speedWith chain protectorBB axle-length: 113mmBolt-circel diameter: 96/64mm Art.
