Chain Whips
Browse used chain whips for sale from riders across the UK. A chain whip is a steel handle with a length of bike chain riveted to it, wrapped around a cassette sprocket to hold the cassette from turning while a lockring tool undoes the ring at around 40Nm. Anyone changing their own cassette needs one, alongside the lockring tool that does the actual turning.
Traditional whip, double-ended, or gripper?
The plain single whip is a handle with one run of chain — cheap, effective, and it needs a decent wrap around a mid-sized sprocket to grip. Double-ended whips carry chain on both ends so one side can hold the cassette while the other frees a stubborn lockring, useful if you also work on threaded freewheels. Cassette-gripping pliers, like the Pedro's Vise Whip, clamp the sprocket instead of relying on chain wrap, which stops the slipping that plain whips do on small 11-tooth sprockets. Check the chain speed the whip was built for: a whip made for 8 or 9-speed chain sits poorly on narrow 11 and 12-speed sprocket teeth.
Do I need one for every cassette job?
Only when the sprockets can spin freely. Removing a cassette needs a whip because the freehub turns; removing a centre-lock disc rotor does not, because the hub body is held. A threaded freewheel unscrews under its own resistance and needs no whip either. What you always need alongside it is the matching lockring tool, and the pair are commonly sold together within cassette and freewheel tools.
What wears out on a used chain whip?
The chain, almost always. Flex it sideways along its length: stiff or seized links will not drape over the sprocket teeth and the whip skips under load, which throws your hand into the cassette. Look for rust in the roller gaps and for stretch, since a worn chain sits high on the teeth and grips poorly. Check the rivets or bolts holding the chain to the handle are tight and that the chain has not started to tear at its anchor point — that is where the load concentrates. On the handle, look for a bend, which means someone has stood on it. On gripping-plier types, check the jaw pivot for play and the cam mechanism for a positive lock; a worn cam releases mid-pull.
What is a fair price for a used one?
Plain whips are inexpensive new, so a used one only makes sense at a real discount and with a clean chain — and buying it in a set with a lockring tool usually gives better value than either alone. Gripping pliers cost several times more new, which makes a well-kept used example the better find, as long as the jaw locks firmly. Buy new if the chain is rusted, stretched or stiff, or if the whip is sized for an older chain width than your cassette uses: the tool is cheap and a slipping whip rounds the sprocket teeth it is meant to hold.
