Oumers Bike Cassette Removal Tool with Chain Whip and Auxiliary Wrench Bicycle Sprocket Removal Tools, Bicycle Cassette Lock Ring Extractor Freewheel Remover Wrench Sprocket Remover

Already had the lock ring tool so intended to buy the whip alone, but the faster delivery made me spend the few extra bucks for the whole kit. And boy, was I lucky -- the center hole in the older one way too small to fit over the axle in my electric bike. Because the motor cable had to exit through the above mentioned hole, I had no use for the included driver and can't say anything about it. Otherwise, this kit seems to be light duty and is probably not for frequent pro usage, but worked for me just fine. Both the whip and the lock ring wrench stood up to the 40 Nm torque without a problem. If you are working on an electric bike (or can't use the internal 1/2" square for some other reason), you'll need a 21mm wrench for the external hex. And If, like me, you also like to tighten things to spec with a torque wrench, you will need a 21mm crow foot.

Works as advertised. I sometimes use spare plumbing tubes to increase torque, but have been successful swapping out dozens of cassettes with this tool.

Tool worked well, didn't have any problems. I do with it came with the 13mm allen wrench needed to remove the free hub body from the hub. It's an obviously necessary tool to fully break down shimano hubs and I would have gladly paid the extra cost if it was included in this package. But nonetheless, I am happy with my purchase over all.

Worked perfect for what I needed. I was able to remove the cassette from the bent rim and install it on the new one. The tools fit snug, but they fit. They all held up just fine for the job.

Useful tool

If you work on bike and want to save money this produce does the trick

very lose tool but gets the job done.

It has everything and more. I was expecting way less given the price, but it has everything you need. Btw, in case this helps someone that searches for keyword Zwift, I got this to remove the cassette from my Wahoo Kicker core and replace it with the new Cog 2. If that's the reason you are looking to buy this, then get this one. You'll get the lockring and chain whip to remove the cassette, and you won't need to use a wrench because this comes with the Hex Key/alen wrench thing. Extremely easy to do.

GaryFisherAdvance2007のフリーが逝かれてしまし、ギアを外すのに購入しました。 この道具のおかげで、なんとか自分で無事修理完了できました。 これがあればギアが簡単に外せます。 自転車屋さんで修理してもらうよりは安いのですが、この道具を次に使うことは有るのだろうか？

Indiscutibilmente si tratta di un prodotto di prima qualità, che svolge a pieno la funzione per la quale è stato creato

Decent tool. Does the job properly, and feels solid. No need to put extra force. Used it twice already and everything went smoothly.

He elegido este juego de herramientas porque es de los más completos entre la gran variedad de herramientas similares que hay disponibles. No sólo incluye la llave "de cadena" que sirve para sujetar el casette cuando lo aflojamos, sino que además de la llave de vaso que se inserta en la tapa del cassette incluye un adaptador a llave allen, y además incluye una llave acodada tipo allen que junto con las otras piezas, forma la llave para apretar y aflojar la tapa que sujeta el cassette. No es una herramienta de calidad profesional, pero eso no quiere decir que sea mala. Para uso de un aficionado a la bici es perfecto, y a mí me ha servido para no tener que llevar la bicicleta al taller para cambiar el casette y lo he hecho por mis propios medios siguiendo uno de los muchos tutoriales que hay por internet. He cambiado el casette de origen de la bici, y lo he podido aflojar sin problemas, con lo que pienso que el par de apriete que tenía es el adecuado. Obviamente, si se aprieta en exceso, al aflojarlo usando esta herramienta vamos a tener que hacer un esfuerzo extra que pudiera romper la llave de cadena que sólo se usa para sujetar el casette mientras lo aflojamos (no se usa para apretar). Si hacemos un uso correcto en cuanto al apriete, esta herramienta nos puede durar mucho tiempo. Yo lo he usado para cambiar un casette SRAM de 11 piñones y es totalmente compatible.

Great product for anyone doing at home bike improvements or equipment change - a must have at this price. At around $20CAD you get a chain whip, lock ring tool, and a wrench sprocket remover. Compared to other well known brands a single one of these items would be the cost of this entire kit. I changed 2 cassettes without any issue and the kit works like a charm! The tools are well made and appear to be quite durable - especially given the value of the kit. 100% would recommend to anyone who owns a bike!
