Review on Oumers Bike Cassette Removal Tool with Chain Whip: Efficient Bicycle Sprocket Removal Set by Kelly Noonan

Fast shipping. Seems sturdy enough for casual use. The chain whip works 100%. However, the cassette tool does not fit the two bikes I work on. I have two cheap mountain bikes that are sold by a major retailer whose initials are WM. I got them for free, so I tried removing the stuck rear sprocket and replacing it with one from the bent wheel for a different one. Although both have 12 slots, the tool is too big to fit in both cartridges. They are marked "Falcon" and "Tri-Diamond". If anyone knows a tool that works with them, please leave a comment.
