Pedro's Bottom Bracket Wrench, Shimano® 16x39 - Professional Flat Wrench

This wrench is a perfect fit for Shimano external bottom brackets. The laser-cut teeth grip firmly without slipping. Feels professional and sturdy. I've used it several times, no issues. Highly recommend for any mechanic or home wrencher.

Solid wrench, fits my Shimano BB cups perfectly. It's a bit pricey for a single-purpose tool, but it works flawlessly. The flat design makes it easy to use with a torque wrench. Happy with the purchase.

The wrench is precise and fits well, but I wish it were a bit thicker for more leverage. It works fine for standard BB removal, but for stubborn cups, you might need extra effort. Overall, a good tool.

It fits Shimano BBs, but the metal feels a bit soft. After a few uses, the teeth are starting to wear. I've had better wrenches. For occasional use, it's okay, but for professional use, look elsewhere.

This wrench is a lifesaver. I was struggling with a stuck BB, and this tool fit perfectly and provided the grip I needed. It's well-made and feels durable. The laser-cut teeth are precise. Great tool to have in the garage.

Works as described. Fits my Shimano 16x39 BB perfectly. It's a bit short, so you might need a cheater bar for tight ones, but it's solid. Good value for the price.

I bought this for occasional use, but after only a few turns, the teeth stripped. It couldn't remove a stubborn BB. Disappointed with the quality. I'll stick with my old wrench.
