THE ROADMAN VERDICT.

A biodegradable drivetrain degreaser for chains, chainrings, cassettes and derailleurs.

Why I recommend it

A clean frame with a black, gritty chain is only half a job. This cuts through old lubricant and road grime quickly, making it the product to use before relubing.

Who it is for

Year-round road riders and anyone maintaining more than one drivetrain.

Who should skip it

Hot-wax users following a solvent-based stripping process or riders who only need light surface cleaning.

What it gets right

  • Targets oily drivetrain contamination
  • Works on chains, rings, cassettes and derailleurs
  • Biodegradable formula
  • Can be brushed or used in a chain cleaner

Where it falls short

  • Needs thorough rinsing and drying
  • Overuse removes fresh lubricant
  • Keep away from brake surfaces
