A dirty drivetrain causes poor shifting & unnecessary wear to expensive parts. The CG-2.4 contains everything needed to quickly & easily clean the chain cogs & chainrings: CM-5.3 CYCLONE™ CHAIN SCRUBBER Clean bicycle chains quickly easily & effectively without the hassle & mess of removing the chain from the bike.
