Shimano Acera 8-speed-cassette 11-40T CS-HG400. A cassette firmly suited to increasing the gear range feel of your 8 speed Shimano gear system. Gives you a familiar feel in the high, power gears with the traditional 11 tooth ring. By the time you’ve climbed to the massive 40T low sprocket ring, you’ll experience the feel of having ‘more’ climbing gears while climbing steep hills. This Shimano Acera 8 speed cassette suits Shimano derailleurs with a suitable capacity – see below for listed compatibility. 
Not changed your drivetrain parts in a while? Never really clean your drivetrain? Think about buying a new chain at the same time you replace a cassette or freewheel, as these parts wear together. Under lubricated and dirty drivetrain parts will dramatically accelerate wear. Keep it clean, keep it long serving!
