Oumers Bike Bicycle Crank Extractor Puller Remover Set with 16mm Spanner Wrench for Square Thread Taper Crank Arm and Crankset

Used it once to put on a new crank last year, may use it again for my new bike. works perfectly fine and the price is right,

I used this to pull a crank to mount an e-bike sensor. Installed perfectly to the crank. I used my own, longer wrench to pull the crank. The tool had no difficulty. Elasped time from threading it on the crank to having it pulled was about 30 seconds.

I use this to pull the crank arms off Native Slayermax pedal drive. Works like it should. If you have a problem breaking one loose place your drive back on the kayak and use a rubber hammer to bump it and it will break free. !00% satisfied.

I know absolutely nothing about repairing or fixing bikes so when my new to me Sunny spin bike needed a new pedal/crank arm they recommend I purchase a tool like this so I could replace the parts. It worked well enough but it did bend and I was really afraid it was going to strip at one point but it did it’s job and I do feel like I could use it again. Ultimate, it worked for the job I needed it for but because it seemed to bend (probably just because of how thin the metal is) I’m giving four stars instead of five.

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.

Used on a stationary spin bike (Poo Boo brand), for a new crank arm set up. Worked quickly. Good quality threads so it locked in. Good tool to have for bike owners.Had another tool from the poo boo customer service that was cheaply made and the threads were ruined right away.

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.

This is a less expensive alternative to the name brand tools. While it does feel a little cheaper (not quite exact tolerances, cheaper metal maybe?) it does work the same way. The handle for example is short and uncomfortable when putting a lot of pressure on it (which is often required when extracting a stubborn crank). I just hook a cheater bar on the end and it worked out OK. It'll do the job.

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.

Does exactly what it says. For the price not sure how you could go wrong.

For what you pay this tool is surprisingly good quality. Does the job well.

The puller worked well. The wrench is a little short and seems a little thin resulting in a lack of leverage and a bent wrench. But for the price it worked, and for $15 I wasn't expecting a high quality tool.

All good, no problem whatsoever
