The Super B Freewheel & Rotor Remover is a workshop essential for removing cassette lockrings and compatible disc brake rotors quickly and safely. Designed with a guide pin and integrated handle, this tool helps riders and home mechanics service drivetrains without slipping tools or damaged components.

If you maintain your own bike, sooner or later you’ll need to remove a cassette or rotor. This remover keeps everything aligned while you apply force, making stubborn lockrings far easier to loosen. It’s especially handy for regular drivetrain cleaning, cassette upgrades, or rotor replacements at home or in a busy workshop.

Who is this freewheel & rotor remover for?

Ideal for riders who service their own bikes, home mechanics building or upgrading drivetrains, and workshop mechanics wanting a stable cassette remover tool. Perfect if you regularly clean your drivetrain, swap cassettes between wheelsets, or replace Shimano-style disc brake rotors.

Who is this not for?

Not suitable for bikes that use non-standard lockring systems outside Shimano-style internal spline designs. If you never plan to remove your cassette or rotor yourself and rely entirely on a bike shop for servicing, this tool may not see much use in your toolbox.

Why we love it

We’ve found tools with guide pins simply make life easier. The pin keeps the remover centred in the lockring so it doesn’t slip under load, which means less frustration and less chance of rounding splines. The built-in handle is also practical for quick jobs when you don’t want to reach for extra tools.

Hot tip!

Always keep the quick release skewer or thru axle lightly installed when loosening tight lockrings. It helps keep the tool seated firmly and prevents accidental slips, especially on older or overtightened cassettes.
