    5.0 out of 5 stars I don’t know what the problem is with some people but the tool was just what I needed.

    It didn’t brake the bank. It worked perfectly for my needs, (pulling the crank arms) and I didn’t find it was cheaply made. If some people are bending this tool it’s because they are using it incorrectly. Don’t use a snipe to get more leverage thus bending it. Just use a rubber mallet and tap it and it works fine.

    Used it 3 times and I think it's still the same. The key arm that comes with it is really helpful, I don't know why other buyers saying it useless, I actually used it instead of my own tool. Lol
    Good quality for home use. But if ur using it 10 times an hour please look elsewhere.

    Reviewed in Canada on July 5, 2025

    That tool is missing a push plate (disc of 17.5mm x 3.5mm thick) that goes between the end of the crank and the tip of the threaded rod. You cannot use the center bolt of the crank for this purpose. If you don't have a lathe to fabricate a push plate, do not buy this.
    Otherwise, the quality of the tool is OK.

    I had no idea what size my threads were but assumed it was generic, so bought it since it was the cheapest. works great, no slippage or anything. got my crank out no problem. the quality is well too. Opened the case and noticed that it mightve been opened beforehand, but didnt really matter cause it was in new condition anyways and gonna use it maybe 3-4 times maximum.

    I bought the two piece set to remove the crank arm from my exercise bike and it worked perfectly. If you're worried about the other reviews stating that the wrench is flimsy don't be. You can interchange the wrench that is provided in this set with any other one that you might have that is compatible. For reference I have a fitdesk exercise bike.

    Pedal come off, pedal go back. I had a bit of trouble because my crank was so rusty, but using a pipe to extend the wrench solved that issue.

    Reviewed in the United States on April 7, 2019

    Excellent tool. Used it to change cranks on Sun, Torker and Cyclepro unicycles. I don’t know about bicycles, but it works great for unicycles. Because they are usually not geared, you need this tool to change cranks for various riding styles. With this tool and extra cranks, by unicycle is like two different ones. Not for isis cranks, but great for most cotterless. You can get one without the wrench for a dollar cheaper, but for a dollar, it’s worth it to not have to dig around for the correct wrench. If you have an isis hub, the tools are a little bit more.
