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.

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

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
