Review on 🚲 Lixada Bike Bottom Bracket Tool Kit - for Easy Install and Removal - Suitable for BB86/BB30/BB91/BB92/PF30 Bottom Brackets by Draven Louton

Please note that the knockdown is made of aluminum and not steel. Why is it important? Well, bearings are made of steel, and steel is much harder than aluminum. When you compress the bottom bracket, you wedge a piece of steel into a strong frame. The bottom line is that this piece of steel must be exactly aligned with the opposite bearing. Well, when comparing steel to aluminum, aluminum will lose out. The drift force on the mandrel bent the edge of the mandrel and wedged the bearing at an angle. I immediately stopped and turned around before damaging the bike's frame. I wouldn't recommend this if your bottom bracket requires quite a bit of force like some brackets do. The aluminum splintered and the bearing seized. If you are smart you will feel the change in torque and stop. If you are inexperienced, you will keep spinning and damaging the bike frame.
