BB squeeze kit

BB squeeze kit

"Press BB" (Pressed Bottom Bracket) is the name of a type of bottom bracket (connecting part between the bicycle frame and the crank) for bicycles, in which the ball bearing (support ball) is pressed directly into the frame instead of being threaded. This type is often used on high-performance sports bicycles such as mountain bikes, because of its larger diameter and external structure that allows the use of sealed ball bearings, providing smoother and more durable performance.
Features:
Construction: The ball bearing is pressed into the frame in the "boot" area (bowl) instead of being threaded like traditional bottom brackets.
Advantages:
Larger size: Allows the use of larger diameter ball bearings, increasing stability and durability.
Increased performance: Helps the crank operate smoother and quieter.
