COTOUXKER Bicycle Crank Puller, Bottom Bracket Removal Tool for Easy Mountain Bike Maintenance and Repair, General, sliver

This comes with the tool to remove square taper cranks from the bottom bracket, as well as the tool to remove the bottom bracket itself. I was able to upgrade to a hollowtech style BB after removing the inexpensive setup my bike came with.

Worked almost well. It comes with BB tool, which came handy.

Used on my E-bike. It was useful and necessary

Bottom bracket tool didn't fit. I bought an another tool to do the job. The crank removal tool did its job.

I was able to get one crank off, but the threads inside the black part stripped on the second, cheap metal. Got the second one off by riding around without the crank bolt. 👎

BB removal not doing this upgrade was driving me crazy mission accomplished!

1 of the 3 tools in the COTOUXKER Bicycle Crank Puller bent - the wrench, see pics. So I had to remove it, screw the puller back together, and use a 12-inch crescent wrench instead. Yes, the longer a part has been on a bike without service, the more difficult it can be to adjust, especially loosen, but this bike was well cared for, had little mileage, I used penetrating oil, had a PVC pipe on the wrench to turn it, and yes, was turning the correct way. The pipe should've bent before the metal wrench did. I could've been injured from the failure! The Bottom Bracket Removal Tool didn't fit my Genesis bike, so I ordered a wrench from a different company - a wrench w/ 3 tabs. The Crank Puller was THE ONLY TOOL of the 3 that was useful for me, at this time, otherwise I would've rated this lower than 3 stars. PLEASE manufacturers, make better products and charge the necessary price to do so. If you do, you will be profitable (in the long run). Putting weak tools on the market is hurting consumers, the environment, and your company, who has to find new customers, as the old ones get wise and shop elsewhere.
