Juice Lubes Stifler brush
Use the Stiffler to scrub your chainring, chain, mech and cassette and use it to 'paint' degreaser and chain cleaner onto your mucky bits.
Short stiff bristles work great on grime and the long handle makes it easy to dive deep into those tricky areas. If you're looking for a stiff Drivetrain Brush to give your bike the full works, this is it.
As with all things, go steady. Excessive rubbing or pressure won’t do any good and could lead to surface scratching.
Please note: You should avoid boiling water or hot parts with the Stiffler.
