Tech talk

As long as there have been chains there have been innumerable ways to try and effectively clean them mechanically from a variety of contaminants that degrade a chains performance over time.

In the current cycling market these consist primarily of:

• Various plastic contraptions that usually contain some type of rotating brush or brushes that clips over the chain while on the bicycle
• Has a chamber containing (usually) a petrochemical-based cleaning solvent
• Is bulky and heavy during use. Not portable.
• Prone to fluid leaking and spills
• Basically impossible to dispose of the used liquid cleaner in an environmentally responsible manner
• Expensive – In the $30 – $50+ range
