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.

The CM-5.3 can handle any bike-specific chain, from wide 3/16″ single-speed* to narrow 12 and 13-speed. A reversible handle allows the chain to pass through forwards or backwards for compatibility with center drive e-bikes.

Compatible with all multi and single-speed chains*
Compatible with center and rear drive e-bikes
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.
