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

After reading the reviews I decided to try it, in the worst case I have to buy another tool. Nicely packaged, the tools look solid at first glance. The freewheel bushing is aluminum, which is not uncommon, and the chain wrap looked decent. The bushing did not fit any of my Shimano freewheels (TZ500-7 or MF-TZ31). The chain wrap didn't have a locking mechanism to prevent the chain from falling and slipping, and is a bit short, losing leverage. I knew there was no turning back so I tried to remove my old freewheel, pushing the bushing back into place, it knocked its teeth out. Save time if you need a freewheel buy a Park FR-1.3, even a FR-2 can work if your slots are in the right place.
