The Park Tool CM-5.3 uses an extra-large solvent reservoir and a series of four rotating brushes to get chains sparkling clean inside and out. A magnet at the bottom of the CM-5.3’s solvent reservoir draws away particles scrubbed from the chain effectively keeping them from being redistributed on the chain during cleaning. The durable sponge material draws solvent from the chain as it exits the CM-5.3 reducing drips and mess.
Compatible with all multi and single-speed chains*
Compatible with center and rear drive Ebikes
Holds 59 mL (2 fl. oz.) of solvent
Replaceable brushes and sponge (part RBS-5)
*All standard bicycle chain sizes will fit through the CM-5.3. However some single-speed bikes are not fully compatible with the CM-5.3 due to the low clearance between the chain and chain stay.
