A clean drivetrain keeps some of the most crucial components working at their best, provides a smoother ride quality and increased longevity; as opposed to a dirty drivetrain, which can cause poor shifting, unnecessary wear and increased likelihood of things going awry mid-ride. Maintain your drivetrain with the Park Tool CG-2.3 Chain Gang System. It contains everything you need to quickly and easily clean the chain, freewheel cogs and chain-rings.
